The Magnetic Sensor should be located near the rotating flywheel magnet.
The Magnetic Sensor wires connect to ground and ESP32 pin 26.
2Arduino Code Modification
The only variables that need to be modified in the Arduino code are the wifi username, wifi password, and belt_distance (measured in mm)
const char *ssid = "Your_SSID_here";
const char *password = "Your_Wifi_Password_here";
volatile long belt_distance = 142;
3Arduino - Board Setup
Use the following partition scheme to fit the program on the ESP32 board:
HUGE APP (3mb NO OTA/1MB SPIFFS)
