Initially we build a transmitter and receiver to communicate between Arduinos using Morse code sent by pulses of light waves. Next, we consider digital music, which we create by switching a voltage on ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

I recently searched for a digital FM transmitter kit, but most of the ones that I found online were either too expensive or did not have enough flexibility for my future applications. So I decided to ...

Future versions of the build will probably be based around the Arduino Mega, allowing for a TV resolution of 720×480. Also on tap are an SD card slot, LEDs, pots, and possibly even headers for ...
