Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED's are used in many applications.

I know very little about electronics, but if you give me a schematic and a pile of parts, I can more-or-less assemble them correctly.I am trying to build a simple circuit to simulate the behavior ...

This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...

Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...
