I’m completely new to this, so I might ask stupid questions.
But: Yesterday I finally invested and bought the equipment I needed to start my Arduino project/experiment/whatever. I wanted to use all the digital i/o pins and wired everything together, only to find that some of them are working the opposite way I tell them.
They are always set to HIGH, and I have to switch them manually to LOW. Even if they are in input mode, I have to tell them to be on LOW.
Srsly guys, WTF?
I’ve had it only for a week. Even the bag was closed, sealed back in its original state. I opened it only for testing on pin 13. (god, I didn’t test the others…)
tl;dr: Some pins are set to HIGH without a reason. What should I do?
SORRY GUYS! I DIDN’T REALIZE THAT THERE IS A TROUBLESHOOTING BOARD! Mods, pls move this thread.
