This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

Last week I explained how to use a motion sensor to trigger an event with an Arduino. The event we triggered was a simple blinking of an LED. You can do a lot with a bunch of LEDs if you use your ...

In this paper, the driver circuits are proposed for Light Emitting-Diode (LED) lamps with a dimming feature. The two different drivers used are flyback converter and forward converter in series with ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...
