pins 5-0 not working

Post by Wildfire »

I just bought the arduino starter pack and my digital pins 5-0 barely work. I was planning on hooking a led up to the pins and have them "wave" down, but the pins 5-0 only give off a very faint light...What do i do to fix it??

Make sure your sketch calls pinMode() to set each pin as an output. Dimly-lit LEDs are a classic symptom of forgetting to do that.
