However, fun and learning are not just for kids. Because of this, it is widely used in educational settings. The Pi is a great device for learning and hardware hacking. You could also attach LED lights and motors to those pins, and use your Pi application to drive those peripheral devices.įor more complex sensors or devices, such as camera modules, you can also connect to the Pi via USB or Wifi, and access them in software. temperature, humidity, light) to those pins, and capture their data from your applications running on the Pi.
