What's the difference between Pi and Arduino? We all know Raspberry Pi is a mini computer running on Linux operating system; while Arduino is a microcontroller running on simple I Os. Both of them focuses on very different areas. Compared with Arduino, the Pi gets much better computing performance. So What happens when a Pi meets an Arduino? A simple example would be, when building a mobile robot, we
