I have read the code... It is using forward button to implement the advance with obstacule detection and avoid if that is detected, isn't it? In the next future, I will merge in the development branch in order to test. Good job! 👍 |

Changes to add a distance sensor (HC-SR04). It allows checking when moving forward if there is an obstacle and if so, move on to the next step.
The default configuration uses expansion pins SDA / SCL / 5V / GND with this scheme:
Arduino <----> HC-SR04
SDA (A4) <----> Echo
SCL (A5) <----> Trigger
5V <----> Vcc
GND <----> GND
