Description

The system uses an ESP32 to connect to a database I made to track Venmo payments and tricks the vending machine into thinking it has money by triggering a relay to signal the dollar bill acceptor. In v1.0, I used the wrongs GPIO pins on the ESP32 and the footprint for the relay was incorrect, so I am updating them here.
