So I'm using an Arduino Uno WiFi Rev 2 with some sensors for a greenhouse project. I've used the circuit before and i think it's a working circuit (all ground bits go to ground, all voltage bits connect to 5V pin etc), and ive double and triple checked.
I've tried powering the arduino using battery and via my laptop. Whenever the circuit is fully plugged in (5V, A0, A2, D11 and Ground) the arduino turns itself off, even while connected to a power source. However, when i pull the ground pin out, the arduino turns on, and performs the example blink code (last code i put onto it).
I can't find anything online and I'm so so confused.
Any help would be appreciated.
