Section Control Using Arduino

Hi everyone
I have just started to look into AgOpenGPS and am wanting to get section control on an old sprayer to work. I have found a few short tutorials but no easy way of using an arduino and some relays to do so. If anyone could help that would be great.

What sprayer are you trying to do this on? Controller? What is your GPS source? I set this up to run 4 sections on a NH sprayer pulled by a NH T7 with intellisteer. I don’t have rate control, only on/off and rate governed by the speed.
