How to do it...

Connect the switches to the GPIO using a method similar to the one we used in Chapter 9, Using Python to Drive Hardware, for the D-Pad controller. A circuit diagram of the switches is as follows:

The switches should include current limiting resistors (1K ohm is ideal)

How you connect to the Raspberry Pi's GPIO will depend on how your motor/servo drive is wired up. For example, a Rover-Pi robot with an H-bridge motor controller can be wired up as follows:
