I wanted to make it so that a LED gets brighter and brighter and then once it hits "full-power" it would loop back to off. I know this can be done using PWM to keep switching the pins between on and off but I have no idea how. The datasheet doesn't show anything I can understand either, and the projects that use PWM can't be adapted that easily.

Anyone care to explain how PWM works a bit? Thanks, and love my Nerdkit so far :D

Yeah, exactly that. Thank you very much, I looked around but didn't find that.

Did you know that you can use a transistor to interface between different voltage levels of digital logic? Learn more...
