Re: [avr-chat] battery-operated AVRs

[Marge Coahran]

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?
