Input and Output controls for Pibrella on Raspberry Pi

A set of configured gpio-in and gpio-out nodes to control the Pimoroni Pibrella

http://shop.pimoroni.com/products/pibrella

Copy and paste them into your own Pibrella applications.

Click a 1 or 0 injector to turn an LED on or off.

Pressing the RED button, or closing one of the four digital inputs gives a debug output (1 then 0).

Note this flow needs the latest version of the gpio-in/out nodes, as it uses I/O pins not listed in the original version of the nodes.

I've also included a couple of demos:

A traffic light simulator - press the "initialise" injector to set initial "green", and then press the RED button to activate the sequence.

Also an input to output mapper example - short two of the input pins and the matching output pin lights up.
