I just need verification that this note in the V1.2 documentation matches the RAMPS diagram in the same section (see photo):
As of the v4.0.0 software released on June 21, 2017, the UTM Pin/Wire A/1 should be connected to +5V on Arduino/RAMPS, while B/2 should be connected to Ground. This change is because the tool verification pin now uses the pull-up resistor in the firmware, so it should be jumped to Ground, instead of +5V. Note: you should double check the wiring of your soil sensor as well.
Do not need assistance any longer. Picture is accurate for V1.2 farmbot.

Hi John,
Can I take it that you have a working farmbot with RAMPS/ARDUINO as opposed to Farmduino? I have just started a custom farmbot and I am keen to connect with anyone who has built one from scratch using the cheap route.
Cheers
