Il mio progetto consiste nel controllare tramite un modulo ESP32 DEVKIT V1 un motore brushless. Sul modulo ESP32 ci sono montati due pulsanti, uno sul pin 18 per aumentare la velocità del motore, l'altro sul pin 19 per diminuire la velocità del motore. Il motore è collegato ad un ESC il quale è collegato tramite il pin 9 ad una arduino UNO. Sulla arduino UNO è inoltre montato (pin RX e TX) un modulo HC-06 (indirizzo mac: 98:D3:31:FD:2D:B5 , pin: "1234"). Obbiettivo è quello di avere i codici (uno per ESP32 e l'altro per Arduino UNO) che mi permettano di collegare l'ESP32 all'HC-06, di poter inviare segnali di aumento e diminuzione di velocità al motore. Nella posizione iniziale il motore dov...
