Raspberry Pi GPIO Extension

The Raspberry Pi GPIO extension allows Scratch to control Raspberry Pi GPIO pins. This extension is only available on the Raspberry Pi release of Scratch 3.0, other versions do not have it.

Blocks

The Raspberry Pi GPIO extension contains four blocks:

• when gpio (0 v) is [high v] :: extension hat
• <gpio (0 v) is [high v]? :: extension>
• set gpio (0 v) to output [high v] :: extension
• set gpio (0 v) to input [pulled high v] :: extension
