He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

For this setup, the program uses only 27 lines, and you'll mostly be dealing with "if" statements, perfect for when you're just starting out with Arduino programming.

He connected the Arduino Mega’s LED output to a pair of LittleBits which then switch a servo between two positions. A bare servo wouldn’t be much fun, so [Outaspaceman] connected a tentacle ...
