Microcontrollers are hidden inside a surprising number of products these days. If your microwave oven has an LED or LCD screen and a keypad, it contains a microcontroller. All modern automobiles contain at least one microcontroller, and can have as many as six or seven: The engine is controlled by a microcontroller, as are the anti-lock brakes, the cruise control and so on. Any device that has a remote control almost certainly contains a microcontroller: TVs, VCRs and high-end stereo systems all fall into this category. Nice SLR and digital cameras, cell phones, camcorders, answering machines, laser printers, telephones (the ones with caller ID, 20-number memory, etc.), pagers, and feature-laden refrigerators, dishwashers, washers and dryers (the ones with displays and keypads)... You get the idea. Basically, any product or device that interacts with its user has a microcontroller buried inside.

In this article, we will look at microcontrollers so that you can understand what they are and how they work. Then we will go one step further and discuss how you can start working with microcontrollers yourself -- we will create a digital clock with a microcontroller! We will also build a digital thermometer. In the process, you will learn an awful lot about how microcontrollers are used in commercial products.

Pass Requirements
•Demonstrate knowledge and understanding of coding principles

•Demonstrate an understanding of hardware components

•Apply them in familiar and unfamiliar situations

•Analyse client briefs so operational requirements can be interpreted

•Develop and deliver a structured system that demonstrates an understanding of the relationship between the program and hardware
Distinction Requirements
•Test the full functionality of the system in a structured way, this includes unexpected events

•Be able to make critical judgements on the conformity of what has been developed which is tested against the brief

•A structured development process must be followed by learners

•Learners must be able to provide technical justifications to support a solution

In this module we will be learning about input and output devices for different functions. For example temperature devices such as thermoresistors and temperature sensors and what instances they will be used in. Also we will exploring output devices and how they function and work to carry out what they need to do so we fully understand how they work and example of an output device well be looking at is electromechanical relay.

The unit is about microcontrollers and how they are applied in engineering. These microcontrollers will be both built and coded in the course. A microcontroller is a computer on a single chip which runs stored computer programs. The assessment consists of 12 hours spread over 3 weeks where you will build and code a microcontroller to solve a problem that the exam board submits you

We would have to show our understanding of a computer coding principles, electronic hardware components and the process when developing them.

Also to apply the knowledge that we already know about computer coding principles, hardware and development process to design and create a physical computer system to meet the brief.
Then we compare and evaluate the evidence to show the performance of a physical computer system throughout the development process.
To develop a physical computer system to meet the brief.

A1-
The control hardware would include:
Input and out put- number, type
Hardware- processor speed
Memory- RAM random access memory
Hardware features- interrupts/stack
Peripherals- keyboard/mouse
Cost and accessibility.

Programing Techniques
Software development involves analysing the given required software operation, writing the program while following DSE guidelines and debugging the software until it works.
Effective coding requires an in-depth understanding of Libraries, variables, operations and logic statements along with knowing know to effectively apply code syntax and structure to keep the code readable.

Parameters to be measured- eg light intensity.
Accuracy and range- oscilloscope.
Cost and availability- hardware and component availability.
Interfacing- adapters etc.
User controls(aesthetics ergonomics)- casing can lower functionality.
Required output/effect- required function.
Electrical, mechanical and dimensional spec- constraints with size and cost etc.
Usability of display devices- LCD displays.
Interfacing and power control requirements- switches, adapters and adjustable components.

Bits and bytes are the types of storage.
Binary to decimal is you consistently devide by 2 to get a 1 or a 0

Development process is the process you go through whilst you are developing a new program for a customer.
You do this by analysing the brief that you have been given and take action according to what you think would be best for the specific thing you are designing, after the initial design you go through a series or assembly, coding and testing the system you have just built.

Along the way you will need to keep your documentation and proof of what you have down in case of any future errors or corrections that need to be made and also so others know your process and justification for what you have done and how you have done it.
