Are you looking to get into the world of Arduino and see what you can do with this technology? Below, there are projects for beginners perfect for a low level of programming. These projects should give you a basic idea of the potential of Arduino and maybe you can find inspiration to learn more about this versatile platform.

Arduino is an open-source hardware design, so everyone with enough knowledge can make their own boards. There are also lots of beginner's kits that include an Arduino board and basic components, such as sensors, breadboard, relays, controllers, LEDs, jumper wires and motors. All projects mentioned below use only the most basic Arduino components.

Arduino Projects For Beginner list

The Knight Rider is simply several LED lights blinking one after another. It's one of the easiest Arduino projects you can find. Before you start, prepare the following components:

10 LED lights

Arduino Board

10 x 200Ω or 220Ω resistors

Breadboard

With this project, you will learn to use LEDs for loops which will help you proceed to more complex projects. Start with connecting everything together.

Always use a resistor or you can damage your Arduino Board and your LEDs. Even though everything can work without a resistor, it is not worth risking your platform.

Take a negative leg of the LED and put it in the negative bar of the breadboard. Take the positive leg and put in the positive bard of the board. Connect the resistors to the LED and to the board with a jumper wire. Do the same for other LEDs.

Now, all you need to do is to upload a program. After everything is done, the Knight Rider should be working. You can change its speed and add more LEDs.

PIR sensor is a movement sensor so every time something moves, it sets Out to High. With this project, you can control the High state and the sensitivity of PIR. During this project, you will learn how to use LEDs and a piezo buzzer and how they can detect motion. Below, there are the components that you will need:

The first thing you need to do is to get all the connections right. You will need to take 5 jumper wires and connect everything. Keep in mind that you should take male-female connectors.

Now, upload the program to your Arduino. Set the frequency to 3,000 Hz. When everything is done, you will hear the sound (just like a blink when you work with LEDs) when your PIR detects the movement. You can change the delay time to change the time of the beep.

With this project, you will use a popular HC-SR04 ultrasonic sensor to allow your robot avoid obstacles and move in different directions. When you're done, you will have a device that will sense the distance and display in on a screen.

Here is what you need to take for this project:

Arduino Uno Board

HC-SR04 ultrasonic sensor

LCD with I2C converter

Jumper wires

Start by making all the connections with the jumper wires. At this point, you shouldn't add your LCD. Now, take an LCD and connect it accordingly. After that, download the library using the Arduino IDE. Just open Sketch - Include Library - Mange Libraries - LCD I2C. And you're done! This is a very quick project that gives you skill necessary to build complex robots.

To make everything easier, it's recommended to take an LCD with an I2C converter so you only need 4 cables to connect it to your Arduino board. The fits loop will be the LEDs setup and the second one is to control the lights. You can change its sensitivity by changing the value in the code.

The aim of the project is to create an Arduino volume meter using LEDs and a microphone. Here is what you will need:

Arduino microphone

10 x LEDs

10 x 200-220Ω resistors

Jumper wires

Breadboard

You can use any microphone compatible with your Arduino board that has an analog output. Moreover, the final result looks best if you take 5 green, 3 yellow and 2 red LED colors.

All you need to do is to connect everything using your Arduino board. Make sure LEDs and resistors are properly connected. Take male-male cables. Then plug the microphone module to the breadboard and you're done.

This is a very simple project to teach you the basics of blinking LEDs built with an asynchronous set. You need to take:

Arduino board

6 x LED of any color

6 x resistor 200Ω

Jumper wires

As you can see, this project uses the most basic elements of Arduino. The most important part is the hardware part. Always put the longer leg of the LED to the positive pin and the shorter leg to the negative pin. Plug the longer leg to resistors and the shorter leg to the breadboard. Always use resistors when working with LEDs.

There are plenty of expensive transistor models for Arduino but beginners don't need them. In this project, you will need a cheap and simple transistor to control a motor. It's a simple way to build a functional H bridge. You will need:

Arduino Uno board

BC547 transistor

47K ohm resistor

Motor

breadboard

Jumper wires

Start with the wires and make sure everything is properly connected. You don't have to use this transistor, almost any other will do the job. Just make sure its current and voltage is enough for your motor.

You can use different resistors, but 47K ohm resistor is very cheap and does its job very well. There are ways to calculate resistor values using a multimeter, but it can be too hard for a beginner so this resistor is recommended.

Rainfall detector is one of the most useful Arduino projects for beginners. The detector will beep, so you will know that the rain has started. For this project, you will need:

Basically, the rain sensor is a simple PCB board that opens traces when raindrops close the circuit. The special circuitry gives a signal to the digital output pin that you can hear. There is also an analog output pin that you can use to read the values from the sensor.

You have full control of threshold for digital output with the potentiometer on your board. Use red LED lights to tell you the rain is detected, and you should touch the sensor with a hand or squeeze it a little bit too see the light. The skin resistance is big and the light will be bright.

You can make your rain sensor useful by putting the sensor outside and leaving other parts inside to protect them from the rain. When the rain starts, you will hear the beeping sound.

The RGB lights is a LED that contains 3 LEDs: red, green and blue. The RGB can shine in millions of color and is as easy to use as a regular LED. And LEDs are perfect for beginners because they are very affordable, easy to use and you can make thousands of Arduino projects with them. But this is one of the most interesting LED type, which is different from other LEDs. For this project, you will need:

Just connect everything together and you're done!

To make the LED light shine brighter, you can use foam that comes in boxes to protect shipped items. Just make several holes for the LED to go in and the foam will start changing its colors.

A stepper motor means a precise motor that can be rotated one step at a time. You can find them in robotics, 3D printers, and CNC machines. Some of them can be very expensive and as a beginner, you don't need them. For this project, take the cheapest stepper motor you can find. The motors are available online.

In this project, you're going to use 28byj-48 stepper and there are many other projects this motor is suitable for. It's easy to connect to the Arduino board. For this project, you will need:

Arduino Board

28byj-48 stepper motor with driver

Jumper wires

You will need 6 cables with female-male connectors. You just need to connect the motor to the driver and that's it! You can also add a small piece of a tape on the rotating head to see that it actually rotates.

Even if you're new to Arduino, you can control one of your appliances with it. For example, with this project, you will use different components to create a bridge from the Arduino layer to appliances with high power rating. For this project, you will need:

Arduino Uno board

Relay board

Cable with socket and plug

Jumper wires

230V lamp

You need to prepare the socket and the cable by removing the insulation from the cable. Then, connect the cable to the socket and connect another wire to the socket. The best appliances to control with your Arduino board are a lamp, a washing machine, and a motor. For example, you can program your Arduino board so that it swatches the power input of your washing machine off at a certain time of the day.

With this project, you will learn how to use a display and how to properly connect it. Displays are used in many other Arduino projects, so learning the basics will be very helpful. You will need:

Arduino Board

7 segment display 3 chars

3 x 300Ω resistors

Jumper wires

Breadboard

One of the easiest ways to connect a display to your Arduino board is to plug it into the breadboard and take male-male cables. Later on, you will be able to plug male-female connectors to display but it's quite hard for beginners. You will also need resistors to connect a LED to Arduino and protect the board from burning, and you should also connect resistors to your display because it's made of LEDs.

The name of the project is self-explanatory. To make the light, you will need:

Arduino Board

Relay

Microphone module

230V lamp

Jumper wires

Cable with a plug and a socket

Begin by connecting the relay and the microphone. Use the analog output of the microphone and connect the relay to the pin 2. When you turn the loud music on, the lamp starts blinking.

With this project, you can build an Arduino stopwatch using the simplest components. You will need:

Arduino Board

LCD with I2C converter

Buzzer

Potentiometer

Jumper wires

Breadboard

All you need to do is to set the time between 1 and 120 minutes. After that, it waits for 5 seconds and counts down. When the time is up, it beeps several times. That's it.

We hope you have been able to build a fully working Arduino project with these ideas. The best thing, you're not limited to simple projects. When it comes to Arduino, there is an amazing community that's all about sharing. Many people are happy to share what they did and you can find thousands of Arduino projects, both very simple and very complex.

In this tutorial, we're going to help you create a few simple arduino projects that are perfect for beginners. These basic projects will help you understand how to set up the Arduino software and then connect the components to perform a specific action.

If you're completely brand new to Arduino, make sure you download our free ebook below. This guide was created for the absolute beginner and will help you to understand the Arduino board along with its parts and components.

In order to complete the projects in this tutorial, you'll need to make sure you have the following items.

At this point, we're ready to download the free software known as the IDE. The Arduino IDE is the interface where you will write the sketches that tell the board what to do.

You can find the latest version of this software on the Arduino IDE download page.

To install the software, you will need to click on the link that corresponds with your computer's operating system.

Once the software has been installed on your computer, go ahead and open it up. This is the Arduino IDE and is the place where all the programming will happen.

Take some time to look around and get comfortable with it.

1. Menu Bar: Gives you access to the tools needed for creating and saving Arduino sketches.

2. Verify Button: Compiles your code and checks for errors in spelling or syntax.

3. Upload Button: Sends the code to the board that's connected such as Arduino Uno in this case. Lights on the board will blink rapidly when uploading.

4. New Sketch: Opens up a new window containing a blank sketch.

5. Sketch Name: When the sketch is saved, the name of the sketch is displayed here.

6. Open Existing Sketch: Allows you to open a saved sketch or one from the stored examples.

7. Save Sketch: This saves the sketch you currently have open.

8. Serial Monitor: When the board is connected, this will display the serial information of your Arduino

9. Code Area: This area is where you compose the code of the sketch that tells the board what to do.

10. Message Area: This area tells you the status on saving, code compiling, errors and more.

11. Text Console: Shows the details of an error messages, size of the program that was compiled and additional info.

12. Board and Serial Port: Tells you what board is being used and what serial port it's connected to.

At this point you are ready to connect your Arduino to your computer. Plug one end of the USB cable to the Arduino Uno and then the other end of the USB to your computer's USB port.

Once the board is connected, you will need to go to Tools then Board then finally select Arduino Uno.

Next, you have to tell the Arduino which port you are using on your computer.

It's finally time to do your first Arduino project. In this example, we are going to make your Arduino board blink an LED.

If you need a refresher on the parts of the Arduino or how a breadboard works, check out our previous tutorial called Arduino For Beginners.

Required Parts

Connect The Parts

You can build your Arduino circuit by looking at the breadboard image above or by using the written description below. In the written description, we will use a letter/number combo that refers to the location of the component. If we mention H19 for example, that refers to column H, row 19 on the breadboard.

Step 1 - Insert black jumper wire into the GND (Ground) pin on the Arduino and then in the GND rail of the breadboard row 15

Step 2 - Insert red jumper wire into pin 13 on the Arduino and then the other end into F7 on the breadboard

Step 3 - Place the LONG leg of the LED into H7

Step 4 - Place the SHORT leg of the LED into H4

Step 5 - Bend both legs of a 220 Ohm resistor and place one leg in the GND rail around row 4 and other leg in I4

Step 6 - Connect the Arduino Uno to your computer via USB cable

Upload The Blink Sketch

Now it's time to upload the sketch (program) to the Arduino and tell it what to do. In the IDE, there are built-in example sketches that you can use which make it easy for beginners.

Now you should have a fully coded blink sketch that looks like the image below.

Next, you need to click on the verify button (check mark) that's located in the top left of the IDE box. This will compile the sketch and look for errors. Once it says "Done Compiling" you are ready to upload it. Click the upload button (forward arrow) to send the program to the Arduino board.

The built-in LEDs on the Arduino board will flash rapidly for a few seconds and then the program will execute. If everything went correctly, the LED on the breadboard should turn on for a second and then off for a second and continue in a loop.

Congrats! You just completed your first Arduino project. Troubleshooting - If you ran into a problem don't give up, check out the troubleshooting section below for common problems.

Change The Code

Before we go to the next project, lets change some of the code in the "Blink" sketch to make it do something different. Playing around with the sketch will help you start to learn how the code controls the board.

Keep the Arduino board connected and change the delay portion of the code from (1000) to (200). Click the verify button on the top left of the IDE and then click upload. This should make the LED on the breadboard blink faster.

NOTE - Arduino measures time in milliseconds and 1000 milliseconds = 1 second. The original code (1000) turns on the LED for 1 second and then off for 1 second. By adjusting the code from (1000) to (200) it shortens the time between on and off which makes it blink faster.

Now it's time to talk switches and how they can be incorporated into Arduino projects. A switch is a electrical component that completes a circuit when pushed and breaks the circuit when released. In this project, we will be using a small pushbutton switch to control an LED.

Required Parts

Connect The Parts

You can build your Arduino circuit by looking at the breadboard image above or by using the written description below. In the written description, we will use a letter/number combo that refers to the location of the component. If we mention H19 for example, that refers to column H, row 19 on the breadboard.

Step 1 - Connect the blue jumper wire from the GND on the Arduino to the GND rail (blue line) on the breadboard near A13

Step 2 - Connect the blue jumper wire from the GND rail on the breadboard near A17 to H19

Step 3 - Connect the red jumper wire from the power rail on the breadboard around row A27 to H26

Step 4 - Connect the green jumper wire from pin 2 on Arduino to J24 on the breadboard

Step 5 - Place one leg of a 10k Ohm resistor in G19 and the other leg in G24

Step 6 - Place the pushbutton switch into F24, F26, E24 and E26

Step 7 - Place one leg of a 220 Ohm resistor in D5 and the other leg in G5

Step 8 - Insert the short leg of the LED in the GND rail around A5 and the long leg in B5

Step 9 - Connect the black jumper wire from pin 13 on the Arduino to I5 on the breadboard

Step 10 - Connect the red jumper wire from 5V on the Arduino to power rail (+) near A8

Step 11 - Connect the Arduino Uno to your computer via USB cable

Upload The Switch Sketch

Now it's time to upload the sketch to the Arduino that will allow us to use a switch. As with the blink sketch, there are example programs already loaded in the Arduino IDE that we will be using.

In order to use a switch, we have to load the file called "Button" which can be found here: File > > Digital >

Now you should have a fully coded button sketch that looks like the image below.

Next, you need to click on the verify button (check mark) that's located in the top left of the IDE box. Once it says "Done Compiling" you are ready to upload it. Click the upload button (forward arrow) to send the program to the Arduino board.

Press the button switch on the breadboard and you should be able to turn on and off the LED as shown in the below video.

If you are having any problems with the projects we did, make sure the following has been checked.

1. Verify the LED is actually functional. Use a 3v coin cell battery and connect the LONG leg of the LED to the (+) and SHORT leg to the (-) of the battery.

2. Verify the correct leg of the LED is connected properly. LONG leg to positive and SHORT leg to negative.

3. Make sure the Arduino IDE shows the correct board. Go to Tools > Board then select Arduino Uno.

4. Make sure the Arduino IDE shows the correct port. Go to Tools > Port then selectthe port that says

5. Verify all component connections are secure with the Arduino board and breadboard.

Step 2: Make a Flex Sensor

Flex sensors are passive resistive devices that can be used to detect bending or flexing. The flex sensor shown in this tutorial is a flex sensor that decreases its resistance in proportion to the amount it is bent in either direction.You can easily make a sensor wider and longer depending upon your project.

Paper

Flexible Cardboard or Plastic

Pencil

Aluminum Foil or Aluminum Tape

Wires

Hot Silicone or Solder

A 2.2 inch flex sensor can range in price from $ 10 to $ 50.

If we think that at least 5 flex sensors are used in a robotic hand project, the cost will be quite high.

Step 3: Creating the Hand

In the finger length, we cut the piece from the styrofoam.

We divide the piece we cut into 3 parts like finger joints.

We shape the sides of the square parts we cut with the help of sandpaper.

We tie each piece together using rubber. We must leave some space between each piece.

We drill all the pieces longitudinally with the help of a pointed rod.

From these holes we pass the wire to the top of the finger. And let's take the knot to keep the wire stable.

Let's cut a piece of foam as much as hand size.

Combine all fingers by hand.

Cut a piece of foam to mount the servo motors.

Connect all the finger wires to the servo motors.

Step 4: Creating the Glove

You can use an old glove for this.

We put the flex sensors we made on the glove fingers.

We fixed with glue or cable ties.

Note that you should not stick the sensors completely in the longitudinal direction. Intervals are good for comfortable movement of the sensor.

Step 5: Connection

The external battery VCC / GND connect to the breadboard.

The Arduino GND connect to the breadboard's GND input

The servo connections we use in this project are as follows;

Orange Input - Signal Input

Red Input - Power Input (VCC)

Brown Input - Ground Input(GND)

All servo motors VCC and GND connect to the breadboard's VCC / GND inputs.

The signal inputs of all servo motors are connect to the Arduino Digital PWM 3-5-6-9-10 respectively.

The sensors have two inputs. One is the GND line and the other is the signal (Analog) line. The signal line is connected to the VCC line by dividing with the help of a resistor.

Step 6: Code

1. Get the Code (Only Copy and Paste)

2. Add the Servo library

3. Define Servos

4. Define Flex Sensors

5. Variable to read the values from the analog pin (flex sensors)

6. Attaches our servos on pins PWM 3-5-6-9 to the servos

7. Reads the value of flex sensors

8. Scale it to use it with the servo (value between 0 and 180)

9. Set the servo position according to the scaled value

10. Upload the code
