A light-emitting diode (LED) is a semiconductor diode that emits light when an electric current flows through it. It is a very useful device used in electronics. LEDs can be used for lighting, indicators, and even data communications. They are also very power efficient and they are used instead of traditional electric lamps because they can be as bright as lamps while consuming less power than the lamps. [Read more...]
Every circut board requires a power supply to operate properly. Usually, the power supply provides+5Vdc or +3.3Vdc to the whole circut board. There are also instances in which the power supply is not integrated to the circuit board and power must be provided by an external or separate power supply. [Read more...]
