We wrote code for the device with a button to send a Particle event to all other devices that says "MOVE" when it is pressed. The code for the device with a fan handles shared events with the data "MOVE" by flagging the fan to turn on.
We ran into some problems with Zhenfang's device being stuck offline and refusing to go into safe mode :(
Is this a good/useful/informative piece of content to include in the project? Have your say!
