I’m new to the community forums but have been playing around with projects for the Particle Photon for a while now.
I have a blog where I am writing up some interesting projects and guides for the Photon.
Two cool projects I have made are:
Laser Tripwire Alarm - http://codefrieze.blogspot.co.uk/2016/06/how-to-make-laser-tripwire-alarm.html
Static Electricity Detector - http://codefrieze.blogspot.co.uk/2016/05/detecting-static-electricity-with-photon.html
I hope you find them interesting!
