[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the pro… ...

The idea behind the project is simple: take a stepper motor, put a needle on it, and connect it to an Arduino. Instant analog gauge, measuring anything an Arduino can calculate.

A USB-connected I/O breakout interfact board for Android smartphones and tablets, it basically turns your phone into an Arduino-style electronics hub, linking external sensors, inputs and controls ...
