[avr-chat] battery-operated AVRs

[Marge Coahran]

Does anyone have experience running AVRs on batter power? I want to give a 
brief demo at a venue without AC. I was hoping that 3 AAA batteries would 
work, since that gives 4.5V and the datasheet says the AVR I am using 
(Atmega8515L) can accept 2.7-5.5V power supply. However, this does not 
work. Perhaps AAA does not produce enough current? Does anyone know if 
using larger batteries (AA, C, etc) would work, and if so what batteries 
I need?
