Ever since the tiny credit-card-sized Raspberry Pi appeared in the market, it has caught the imagination of every electronics and computer hobbyist around the world. The powerful Linux OS, combined with its 26 I/O pins, can do many amazing things out-of-t

Besides GPIO (General Purpose InputLOutput) pins, the tiny Raspberry Pi has a I2C (Inter-Integrated Circuit) bus, a rART (rniversal Asynchronous ReceiverL Transmitter Serial) bus and a SPI (Serial Peripheral Interface) bus for connecting several kinds of devices. For the OS installed on the tiny Sa card, I prefer aebian Wheezy Linux, for it’s a aebian type and easy to install.

To control Raspberry Pi's (or ‘RasPi’) seven GPIO pins, there are simple Python programs. With a few lines in Python, one can control these pins, making them high or low. Combined with other programs, these pins can do many amazing things. However, here we will do some simple programs like switching some LEas with these GPIO pins. Many interactive games can be designed with the help of these GPIO pins. The possibilities are endless, depending on your imagination.

However, since I love PHP, I always try to do the equivalent of most code in PHP—and when I search the ket, I finG WhHUH Ls usuDOOy D sLPSOH wDy WR GR WhLs.
