This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...

A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

The function of an LED is to emit light when the device is forward biased within its operating range, and it’s known by most ...
