Have you ever wanted to control an army of cockroaches? We’ve all seen remote control cockroaches before — and they really are quite a fascinating specimen to work with — but did you know you can control one for about $30 worth of components, with a Arduino Micro?
It’s actually pretty simple. By stimulating a cockroaches antenna with variable frequencies (to mimic neural signals) you can convince the cockroach that they’ve hit a wall and should turn the other way. What results is a remote-controlled roach. How cool is that!
