Face the reality: Install PiFace Digital

PiFace Digital is a interface board for the Raspberry Pi 1 B. It allows to control relays, LEDs, buttons and some more. For using PiFace Digital on a Raspberry Pi 2 or B+, a 26 Pin Gpio Connector Header Extender is necessary.

The two black blocks are relays which can(inofficially) trigger up to 250V devices.

A PiFace Digital stacked onto a Raspberry Pi B

After installing the Serial Peripheral Interface Bus SPI, shutdown the Raspberry Pi, stack PiFace digital onto it and boot.

Install PiFace Digital, its emulator and the scratch handler
Enter in the terminal

Usage example – Whack a mole

Try the sample code on Github, check out the documentation or this great introduction from raspberryconnect.com.

Raspberry Pi 2
As of march 2015, the whack-a-mole didn’t work as intended on the Raspberry Pi 2!
