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.

thanks!

I would suggest programming a Attiny 85 using your arduino here is a good instructable.If you use a standalone arduino that would quiet overkill it and would be costly to just make a LED glow.

use an Attiny if you want to save space. An attiny13V or attiny45V will run of 1.8V and even use only 240uA at 1Mz.

hello
if you want LED to shine ,LED of voltage common between 2.5V to5V;
for AVR,for example,mage8L working voltage between 2.7 to 5.5V,mage8 working voltage between 4.5 - 5.5V;
beingo means ATMEGA8 and ATMEGA8L :-)
