The Raspberry Pi is a credit-card sized single board computer, working with Linux it’s one of the cheapest computer which exist, $40 for the Model B. The difference between Model A and B is the RAM, 256MB for the A and 516MB for the B also the number of USB connector, just one for the A and 2 for the B also the model B is equipped with a Ethernet connector. For this project I used a Model B. To programming with this card you have a lot of possibility, like C language, Python, Scratch …
