To make a project more permanent...could one pull out the atmega chip from the arduino (the older ones anyway) and solder it onto a perf board?
Would it be as simple as grounding it and powering it and then connecting whatever sensors you have to its pins?
would that work?
could I buy a bunch of these to use? http://www.mouser.com/search/ProductDetail.aspx?qs=K8BHR703ZXguOQv3sKbWcg%3D%3D
could one use the arduino board as a programmer like that?
for the pull up resistor...that would be a resistor going from RESET to Vcc?
and the capacitors...those are .22uf, correct?
would it be so bad to have the arduino use it's 8Mhz clock?
Would you need a voltage regulator to run it off of a 9v battery? Or is that what the caps are for?
