Whole project with raspberry and particle? (Just a newbie)

When using a Particle device and a Rasperry Pi, any project limitations are probably only in your imagination. There are some limitations that you may run into on the Particle devices (Photon, Electron) mostly due to limited memory and flash space. However, if you are using a RasberryPi in conjunction with a Particle device, then a lot of those memory limitations go away since you can do the heavy processing tasks on the RasberryPi and then send publish/subscribe events to the Particle devices when needed. While I do not have a RPI to play with, I do believe you can trigger just about anything on a Particle device from the RPI. The RPI can also be added as a Particle device and connect to the Particle cloud by loading the Particle Agent.
