In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

IntroductionIn a circuit that lights up an LED, it is standard to connect a resistor in series with the LED. So, if the power supply voltage is 10 V and the resistor is 1 kΩ, how many mA of current ...

Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...

[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in his ...

LED drivers control the amount of current and voltage supplied to light emitting diodes (LEDs). An LED driver IC is an integrated circuit (IC) that provides brightness control and backlighting color ...
