Reusing the same Bitcoin wallet address is a big privacy issue. If you have a simple e-shop or a website which asks for donations you may want to consider generating unique addresses for each transaction instead. There are numerous payment systems such as Bitpay that do all the hard work for you. The drawback is that they are in charge of your private keys. You may implement your own simple. I think at best Ardino would be best used to co-ordinate work chunks for the pipelining problem of SHA256 hash calculations (mining) to a series of boxes or racks. Bitcoin uses point multiplication on the Elliptic Curve secp256k1 to generate a public key from a private key. Basically, this curve has a defined Generator point G, and a method for 'adding' two points together in a way to get a new point (EC Point Addition).

Setup
Usage
Security
This is a way to generate a Bitcoin private key which can then be used to send and recieve bitcoin. This way is not entirely secure. I would recomend using a computer that has never touched the internet or a raspberry pi that has never touched the internet. If anyone gets your private key they also get full control of your bitcoins.
Disclaimer
This is my first bitcoin code and I am new to python.
Update
Now using the Entropy library on Arduinos that support it (i.e. Arduino Uno and newer Arduino Megas). This library is tested to be random. It is useful in cryptographic situations, such as this one.
Private keys are now written to the EEPROM on the arduino. Using the sketch Read_EEPROM.ino will readout the key that is stored on the arduino. You can see this in the arduino serial monitor in hex, or you can run it with generate.py to re-generate a compressed private key or a public address. IT ONLY STORES ONE PRIVATE KEY AT A TIME. EVERYTIME YOU RE-RUN THE RANDOM ADDRESS CODE, YOUR PRIVATE KEY WRITTEN ON THE ARDUINO IS OVERWRITTEN.Everything is compressed into one arduino sketch and one python script.
