In which we burn an arduino boot loader onto the ATMega, and then upload our own programs.
In which we add the crystal, finish wiring and insert the chip.
It was suggested to me that I should publish the actual circuit diagram of this project, together with a parts list. Here it is!
This is part two of a short series on how to build your own arduino-compatible board from scratch. You can find part one here: http://www.martyndavis.com/?p=105.
Note: this was going to be one post but it’s ballooned into a huge thing so this is one of several which will be posted over the next few days. Stay tuned!
So you’ve got a nice Arduino board for experimentation and you’ve built a circuit on a breadboard which you’d like to make permanent.
It’s expensive (and overkill) to use a new arduino each time you build a new circuit you want to keep. Here’s how you can easily build an arduino-compatible board, from complete scratch, for a few pounds/dollars/euros so you can keep your real arduino for experimenting with…
