The PS2 game controller
The PS2 game controller can be used to remotely control our robot cars, robotic arms or other devices. There is a
project 
showing how this can be done for an Arduino.
We need to find out, however, how to connect the receiving module to the ESP32 and a driver is needed to receive the commands from the command unit.
Here is the pinout:
