It should be GPIOs. The teensy pins control a ULN2803 that controls the relays.

Figured it was some simple setting that I was missing lol
Hard to say it was a bad day, when I went from sections still glitching for me this morning, and by 8:00pm our 19 acre field of corn is successfully planted! Here’s a few pics and videos of the action.

Great videos! Looks like its all working good.
Yup! Works great! Thanks for all the “product support” you’ve given me in this project!
I built the RC12 rate/section control for a 3 point hitch sprayer we had on the farm. It would occasionally freeze when the sections were rapidly switching to cover small areas. I fixed the problem by adding diodes across the solenoid coils to reduce the reverse current spike when the sections were switched off. You mentioned problems when the sections switched off. If you continue to have issues this may help.
