You need to understand the concept of Bitcoin
You need to know the computing power of the Raspberry Pi, which is much less effective than the graphics card mining, the baked cat, the USB mining, etc.
If you want to toss it, come on. 2. Prepare:
You want to dig Bitcoins, first of all to know where to dig Bitcoin, Bitcoin is in a mine, so we register the mine pool account

On-line tutorials, general Python with Rpi.gpio to control the Raspberry Pi Gpio, and C + + generally use WRINGPI library to operate Gpio,rpi.gpio too simple, many advanced features do not support, such as I2C/SPI library, etc., but also lack of high-precision timing and other advanced features. In contrast, WIRINGPI is rich in functionality, but in fact WRINGPI already has Python bindings that can be very
