Build a Pokemon Detector With Raspberry Pi
To keep track of which Pokémon appear in your area, Pokémon Go usually requires your phone to be open and working. At Adafruit, they demonstrate a way to build your own Pokemon detector using the Raspberry Pi Zero.
This guide walks you through the setup process to create a small device that warns you with a light anytime a Pokémon is around. The catch here is that this is against Pokémon Go’s terms of service, so you risk getting banned at some point. However, it’s a fun project to do for yourself, even if you don’t use it on your main account. Visit Adafruit for a complete guide.
