Simple PiFace input switch/button example circuit

Former Member over 11 years ago

I am looking for a simple circuit setup for reading external(not PiFace on board buttons) push button event.

I have PiFace and push button, I want to setup a circuit and read button push event using Python 3.

any help will be much appreciated.

Hi Sharique,

It is described at this URL. According to this, the input connections on the PFD are already internally pulled-up to 5V (meaning through a resistance). Therefore, all you need to do is connect one wire of a switch to the input, and the other wire to 0V.
