Core3duino

Step 7 Play!

Now you are ready to use your Core2duino.

Upload some code and see if it works!

I have written a test sketch that turns all digital pins on and back off to test them. Upload the sketch to both Atmega168 chips and check to make sure all pins get power on both chips.

Once you establish that it works, put your thinking cap on and build something that requires 40 I/O pins and then message me and tell me about it!

 it's amazing, the text on this page is exactly like that on the last page of the core2duino instructable.  BTW, this is overkill.  For the cost of a duemilanove, core2duino and core3duino i could just get an arduino mega, probably easier to use.  I wonder if hackaday will feature this?

 Yo dawg, we heard you like arduinos, so we put an arduino, on yo arduino, on yo arduino so you can prototype while you prototype while you prototype!

Yes, I said that in the instructable, It is essentially the same as the Core2duino.  And yes, this is overkill, you might even say "this is stupid" as is etched on the pcb. Hackaday making fun of the Core2duino was actually what prompted the idea in the 1st place.

I won't defend needing the core3duino, but there are times when having 2 separate cpu's is a must. While testing my larger bots, I always use 2 Arduinos to decode the drive and failsafe r/c channels separately. That way if something goes way wrong or the code doesn't work as it should, you have a way to shut the thing off before it busts a hole in the wall and your wife tells you no more inside testing ;)
