 We used Mouse devices which where re-soldered to use the 4 USB wires as 'short to GND' to work as controllers. 
 
+One way of wiring everything up (you can vary for geometry reasons) can be seen here.
+We respected the types of PINs and their capability. i.e. all switch pins must support
+pull up resistors (configurable property of ESP32). The buzzer sound pin must be supported by
+the PWM generator.
