Hi all,
I built my own motorcontroller with an Arduino Nano and a Pololu-Bridge. It connects to my Tinypilot via UART... so far so good. But the voltagemeasurement shows 20.43V and makes a BADVOLTAGE_FAULT.
I measured the pin A0 and I see 5,7 Volts, regardless of the voltage, I connect to my board. So I think the Arduino treats the pin A0 as an output. Where else should the 5,7V come from?
any ideas?
