Glowing LED arduino/ATmega/AVR question?
Hello! I have an Arduino Duemilanove running a very simple glowing LED program. I plan to build a small device to house the LED and I was wondering what my options were for using a stand alone ATmega. Most importantly I need to know how small or low voltage of a battery I can use to power the one LED and the ATmega. I'm also open to any suggestions that go beyond the arduino.
