Haha hey, I did a lot of work with the Arduino a little while ago, maybe I can help with this project. Here is an example of a little program I wrote to bit bang PWM to some RGB led's:

Good luck!
Topic: Arduino Miner? - page 2. (Read 31550 times)
I'd be happy to play around with this/improve this if you can get some initial code running :-)
The Arduino microprocessors are really weak so you'll probably not get much out of them in terms of Hash/s. What might work is wiring up some custom SHA256 IC's and using the Arduino to farm work to them - of course with the PC doing the comms.
Sounds like a cool little project, when I read the topic I thought it was going to be someone with plans of clustering thousands of them 
. Maybe you could port the following CPU miner using the assembler hash above:

I haven't used it but checked the code and it looks pretty clean and un-bloated. What were you planning, getting work from the PC and pumping work and results over the serial port, or using a shield to do the network comms directly from the AVR?

I don't have an Ethernet shield, so I'll probably have a program on a PC to do the JSON and feed work to the board. That link looks pretty useful; there's also a fairly clean-looking Python implementation on the same person's Github.

looks like someone already ported SHA256 to lolduino, you're halfway there!

Hey,
Does anyone know if there is a miner available for the Arduino already? I know it probably wouldn't be cost- or power-effective to mine on an Arduino, but if nobody else has done it yet I was thinking of attempting it.
On that note, is there documentation on the mining algorithm? What do I need to do with what I get from getwork?
