Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

http://www.microchip.comLEDs have been a mainstay in modern electronics for over 30 years. Their design requirements are common knowledge, and most designers don't ...

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 ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

"Cute circuitry" is not a term you hear often – if at all – but it could be used to describe Chibitronics, which is a crafty merging of electronics and paper. The system combines familiar adhesive ...

This project is a wonderful example of what can be accomplished with a rather complicated logic circuit. It’s an Etch-a-Sketch made from a 16×16 LED grid. That in itself is only somewhat interesting.
