I’ve recently finished assembling my new Genesis 1.5 kit, and I’m having some trouble reading sensors on the UTM tools. I noticed that my tool verification sensor always reads 1 (No tool) whether a tool is attached or not.
I tried connecting the pogo pins (B and C) on the UTM with an alligator clip jumper and still read 1 (No tool). Out of curiosity, I measured the voltage across pins A and B and saw 0V which seemed odd, since A should be 5V and B should be GND.
I disconnected the UTM cable from the Farmduino and connected / measured the pins labeled for the UTM on the bottom of the Farmduino board. I noticed…
- Tool verification reads 1 (No tool) when I connect pin C to pin B
- Tool verification reads 1 (No tool) even when I connect pin C directly to GND.
- The voltage across pins A and B is always 0V
- The voltage across pins 5V and GND (the pins above A and B) always ready 5V
Everything else works just great – the servos all work, as do the rotary encoders, peripherals (lights, solenoid, vacuum), and camera.
My gut says that something might be wrong with my Farmduino. Does anyone have any advice for further debugging or troubleshooting?
TL;DR - My tool verification always reads No Tool, even when I connect pin C to GND on the Farmduino board directly.
