I am trying to trouble shoot why one pin (0) isn't working on my Seeduino. I am attempting to power an Led with it. I have tested the Led on different pins and know the Led works. For some reason I am not able to use A0 or D0 to turn on an LED. Its a RGB so I want to vary the power, which is why I would like to use the pin as an analog. I've tested three different seeduinos as well, all the same issue. Looking at the pin out I don't understand why that pin fails.
Which Seeeduino. There are many different ones.
A0 is usually an analogue input and digital I/O.
Never an analogue output, so you can't vary the brightness of an LED with that pin.
For that you need a PWM output.
Leo..
Thanks! I tested it and you are absolutely right. I appreciate your time to help me!
