When connecting peripherals to the joystick, it will not be able to run from batteries anymore, so I'm running it from a DC power supply. Since the joystick assumes a 5V power supply, I've build a 5V voltage regulator circuit. The regulator is connected to the output of the battery pack (see picture). NB! Remove batteries before connecting external power. | |||
