How do we use the pogo pins?

I am working on a school project utilizing the 1.3v Farmbot, and my team and i are having trouble understanding the pogo pin connections. We had made an end effector to encase a linear actuator but when we connect it to the UTM, itll rapidly actuate for a moment then stop.
How would we be able to control when it actuates?

Hi @Student the v1.3 FarmBot Documentation is extensive.

Here’s UTM wiring : Wire up the UTM | FarmBot Genesis Documentation
Check the section headed Pin mapping :slight_smile:
