PiFace Digital 2 I/O Expansion Board [discontinued] _ARD_SHIELD_INPUT Unused inputs should be tied

Unused inputs should be tied to ground

so you don’t need an Arduino or any other microcontroller

you might want to try the Series 1 instead

In order to make your repair as smooth as possible we have assembled the ideal toolkit in a handy tool roll with a secure hook-and-loop closure

Temperature Sensing with RTD

PiFace Digital 2 I/O Expansion Board [discontinued] _ARD_SHIELD_INPUT Unused inputs should be tiedPiFace Digital is designed to plug on to the GPIO of your Raspberry Pi, allowing you to sense and control the real world. With PiFace Digital 2 you can detect the state of a switch, for example from a door sensor, a pressure pad or any number of other switch types. Once this state has been detected, you can write your own software for the Raspberry Pi that determines how to respond to that switch state. You can drive outputs to power motors,
