Using Arduino General Electronics

hi,
just wondering how to use these pins, if i wanted to use D1 id have to turn off serial print, and the pin would behave normally?
and just wondering how D0 behaves, can i use this pin for high/low outputs?
thanks

Yes, you just have to not use any serial commands in your sketch, so if no serial.begin() statement then you are free to use the digital pins 0 and 1 as you please. However keep in mind that if you physically wired anything to those two pins you may not be able to upload new sketches from the IDE unless you first electrical disconnect whatever you do have wired to those two pins.

Same applies.

thanks, ive already downloaded the sketch into the ic and its sitting in a pcb, i was getting a bit short on pins thats all, had trouble with using these pins in the past just didnt know you had to turn off serial
