I think I broke the GPIO
In my other question, Pi works, GPIO part will not cooperate, I successfully got the LED to light up, but it would only light up if I used certain pins, it wouldn't work with the 3.3V or 5V pins, it was working with only two GPIO pins,
I was searching for other pins that could supply power and then it cold restarted at the touch of one of them.
My LED turned off, and when the RPi turned back on, my LED did not. I thought I had blown something, so I switched out my wires, resistor and LED for new ones -- and still, nothing lit up.
The odd thing is that I am still able to restart the RPi by touching the ground to one pin, so I think my GPIO interface controller isn't broken, but I am not completely sure, what can I do to test if it is broken, short of a multimeter or voltameter?
It turns out that all I needed to do was unplug it and let it rest. I plugged it up today along with a set of buttons and all sorts of novice things. One thing that puzzles me though is this
The cathodes are the long leg?
Yes, my LEDs for some reason, only work when I use the long pin as the cathode. Anyone know why that may be?
