A diode is a two-pole active component which is generally a semiconductor, which allows electric current to flow in one direction (forward bias) and inhibits current from the opposite direction (backward bias). Diodes can be likened to a valve function in electronics. Diodes do not actually exhibit perfect alignment characteristics, but rather have complex current and voltage relationship characteristics that are not linear and often depend on the technology or material used and the parameters of use. Some types of diodes also have functions not intended for rectification use.

Solder or soft solder is a metal alloy that melts easily, which is used as a filler metal to join two metal materials
In certain proportions, some metal alloys are eutectic, that is, alloys with this ratio give the lowest possible melting point than mixtures of other ratios.
and also coincides with its freezing point. Noneutectic alloys have different solidus and liquidus temperatures, because such alloys have different melting and freezing points.

What is a Capacitor? A capacitor is a two-terminal electrical device that can store energy in the form of an electric charge. It consists of two electrical conductors that are separated by a distance. The space between the conductors may be filled by vacuum or with an insulating material known as a dielectric.Capacitors are crucial components in most electronic devices. They are widely used in electronic circuits, power circuits, power supply units, etc. Capacitors are considered as one of the Big Three Passive Components, along with resistors and inductors, which form the basic electronic circuits.

•What is an ultrasonic sensor?
An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves.
An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity.
High-frequency sound waves reflect from boundaries to produce distinct echo patterns.
•How Ultrasonic Sensors Work.
Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing.
•Why use an Ultrasonic Sensor?
Ultrasound is reliable in any lighting environment and can be used inside or outside.
