Hello,
I have an Mkrfox that turns a relay on/off depending on an ultrasonic sensor's value.
The problem is, the code only works if I click "upload" on the arduino IDE, meaning it doesn't work if I just power it with a battery or via USB.
I should also note just in case that each time I upload the code, I get the following error (couldn't find a fix for it, don't know if it's related to my problem) :
