Hello fellow hobbyists,
I'm pretty new to using the arduino, but I decided to create a watering system for a plant using a moisture sensorand an externally powered solenoid valve.
When I programming it, I (stupidly) had the 12v power supply still plugged in and I figured I accidently shorted 12V to the arduino ground and in the process it went through the USB and bricked my laptop. That's my guess anyways.
Anyone have any tips for a beginner so this doesn't happen again...
Poof there goes $1K.
