Hi and welcome to the story of talking walkies! (See what I did there) Anyway, this project was selected for our MEGR 3171 class and is a great way to get introduced into the IOT Photon world. Luckily we were able to follow an already built project write up from David Middlecamp that includes everything from list of items, diagrams and code. Hopefully we are able to add a little something whether its just tools or an STL for a case.
Now you and your buddies can talk to each other across campus. Texting and snap are a bit overrated now a days. Lead the revolution with one of these bad bois!
I did not come up with this myself so I will let you revert back to David's page for the insight to what is going on.
