The program is for Arduino ESP32, have advanced features as:

- Web control (not need an app, just an browser)
- Motor control by virtual joystick
- Slow speed by PMW over PWM, with higher torque
- Optional OV7670 VGA camera with servo
- Accelerometer to anti-rollover system (not yet develop)

Installing

First have some library dependencies (please help the authors give a github start on it):

- Arduino websocket:        https://github.com/Links2004/arduinoWebSockets
- ESP32MotorControl         https://github.com/JoaoLopesF/ESP32MotorControl
- RemoteDebug:              https://github.com/JoaoLopesF/RemoteDebug
- SerialDebug (optional):   https://github.com/JoaoLopesF/SerialDebug

After install it, just upload this firmware to ESP32
