What do you do when you find your old Game Boy? Most of us try to boot it up and reminisce the days of playing Tetris, Super Mario and Pokémon. Others like Gautier Hattenberger decide to turn it into a drone controller.
In order to do this, Hattenberger modified the Game Boy’s Game Link port with an Arduino Nano and an FTDI chip, which converts the Game Link signals to USB. Using a small piece of software on his laptop, he is able to control his Parrot ARDrone 2.0 via the classic device— A and B buttons for up or down, and the directional arrows for maneuvering.
Hattenberger has detailed his entire build here, and shared the code on GitHub.
