The RPi is based on a 32 bit processor and complex operating software. Great for things that need a web interface or have to interact with complex protocols. You wouldn't consider something like a RPi if you could get the reliability and ease of implementation of a simple program running on an 8 bit processor.
- kefka 12y agoI agree. Where the Rpi<>Arduino combo comes in is where you need PWM and analog inputs in an easy form factor. Arduino talks to RPi over USB serial, and is easy to script. The Arduino can be the controller interface while logic can be done on the RPi. Also if you're doing computation expensive things (like using Arduino to pick up EEG data), the CPU on an Arduino is sufficient in ferrying the data to a faster CPU.
- bigiain 12y agoI know I'm living in a pretty small world of likeminded people and startup IoT companies, but it seems to me _everybody_ hits on the idea of "RaspberryPi + Arduino", then iterates until they end up with some very familiar looking ARM SOC + Atmel 8 bit microcontroller. It's astoundingly common. (And that's because it's a really good idea.)
