Topic: Can I use the programmed chip? (Read 534 times) previous topic - next topic


After I've done all the programming and testing with arduino board. What should I do to take off the microchip and use it in my project, on my board? Should I just follow the data sheet  then? :-?


You will ned a few components, the 16MHz crystal for the clock and a couple of capacitors and the resetswitch.
And of course a well regulated power supply.

Heres a how to from the playground : http://www.arduino.cc/en/Main/Standalone
It's for the Atmega 8 but i believe that it's valid for the 168 as well

might be interesting if you want to be able to reprogram the processor outside the Arduino board.




Here's another example, fewer components and two 168's sharing the same resonator - the circuit works fine with one IC.


You'd need to add a 5v regulator if you don't have a mini USB.

Here's another link you might find useful.



Thanks, that's what I was looking for!  ;)
