Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. Advertisement ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Instead of the relative horror of driving 40 LEDs with a single Arduino, ... control the entire circuit, [Martyn] used an Arduino loaded up with a ... used surplus military components in the ...
