Apologies if this is the wrong forum for this question, but it seems the most appropriate.
After building a circuit and writing a sketch to drive three panel meters, I'm seeing odd behavior when I remove the ATMega328 from my Duemilanove, and place it directly into the circuit.
I've based my Breadboarded circuit on this tutorial:http://arduino.cc/en/Tutorial/ArduinoToBreadboard
The sketch basically does continuous analogWrites to pins 9, 6, and 5.
When the circuit runs directly from the Arduino board, everything is fine and stable.
However, when the circuit is transplanted to a breadboard, I'm seeing "noise" in pins 6 and 5.
I've checked and double checked my connections and don't see any problems - it's driving me batty!
Of course, I'm at work right now and don't have my sketch code or pictures of the circuit to post!
(How's that for asking for something based on nothing?
I will post them as soon as I'm back at my own computer.
The environment is Ubuntu Linux 10.04, running Arduino 0018 (pre Uno).
Thanks in advance for any help!
