The Raspberry Pi and Arduino are complementary platforms and one doesn’t exclude the other. If you combine their capabilities you can achieve amazing results. But why would you use Arduino?
- The community! Arduino has a lot of materials readily available online, from libraries, to examples. If you have something in mind probably someone has already done it and shared the documentation.
- Uses very little power and boots very quickly.
- Runs at 5V logic level whereas the Pi digital pins operate at 3.3V.
- Incredibly cheap hardware which is useful for powering/controlling prototype electronics which might end up damaging your controller. You have to be more careful with a Pi as they are more easily damaged and more expensive to replace!
- Real-time capabilities are more readily accessible whereas there are limitations and constraints to getting the same performance from the Linux-based kernal in Raspbian.
