I was wondering if there is a way to control the power source that come out of atmega. Since they all come out around 4-5 volts. So if i wanted to change the voltage that come out of the atmega to be 2 or 3 volts. how would I go and do that?
Thanks
Sorry. Maybe its better if I put it like this. Say the example Blink on the arduino example. If I removed the digitalwrite (13, LOW) then it would stay lit. So its there a way to lower/raise the power so that the LEDs would go dimmer/brighter??
