Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

A Charliplexed LED heart circuit is being controlled by an Arduino system and can be useful in times of Valentine’s Day. A Charliplexed LED heart circuit is being controlled by an Arduino system and ...

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 ...
