Here we share some practical examples of how to use perimeter detect with ProtoKit 4 - more ideas to be added soon…
Cable Connect: External Perimeter Circuits
If you want to build perimeter circuits outside of the protokit box, then the simplest way is to use a microUSB extension cable.
Adapter Connect: Internal Circuits on ProtoKit4
If you want to build perimeter circuits inside or around the protokit box then use an Adapter to connect the microUSB to the ProtoKit board. Buy Adapter >
Fitting Adapter to Zymkey4 and ProtoKit4
Using Perim Circuits on ProtoKit4
The Adapter makes the following four perimeter signals available on the protoboard:
Examples Of How to Use Perim Circuits on Protokit4
A security shield/mesh that covers the Pi.
This is fitted into the lid of the ProtoKit 4 and pogo pins connect the top mesh to the the bottom board. When the lid is closed, the circuit is closed.
