Hi all. I am relatively new to IoT devices and programming but I thought I’d dive head long into a project I’d actually want to get running to learn how to do it. Crazy, I know.
Here is my idea that I have very little idea how to get running.
I want to make a gift for my siblings. These gifts would be an LED connected to a Photon, powered by a wall plug, connected to their various networks, and these lights would all be interconnected. When sibling A activates his light (saying “Hi”), it would turn blue. Then, in response to sibling A activating his light, siblings B, C, and D etc. would have their respective lights activate blue as well in whatever location and network they are located. In response, sibling B could activate their light saying “hi” in return and thus push their selected color onto the other lights, possibly with some pulsating because it was a response to sibling A first saying “hi”.
To start with, I already have two photons, two neopixel rings, and the power supplies for hardware. I have them both wired up and I have loaded simple projects that I have found online to make sure my neopixels are working and wired correctly. Both photons connect to the internet just fine.
Where I am now having problems is how to I tell the photons to look for the “Hi” that another lights are sending? I’m assuming I’d have to program in a publish command and use the cloud to manage sending and receiving the publish commands? Would I also need to add a subscribe function? How then could I set up a return “hi” to the other units? I’ve already spent the better part of a couple days to no avail and am back to the drawing board as it were on my coding. Any info/advice/sarcastic comments are greatly appreciated and welcomed.
I’m sure I’ll have many more questions arise but I feel like this is a good start.
Thanks and I look forward to your help.
