Re: [avr-chat] battery-operated AVRs

The circuit load is small. I want to drive a 7-segment display with one AVR, and a piezoelectric speaker with another.

I had not been using a bypass capacitor, so I have added one.

Perhaps my misunderstanding is about the AVR. I have programmed the chip, and I thought that simply giving it power would cause execution to start. Is this correct? Do I also need to pull reset low to start execution?

Hello,

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?

That depends almost exclusively on the load/circuit you're using; can
you give any more information on what's connected to the AVR?
