I used to forget my keys when I went out of home so I thought: 'How about using something that I always have with me to open the main gate of my building'. So I put hands on work with my Photon to develop a web app that can be used on my mobile, thanks to the magic of Particle Cloud.The project
The project mainly consists on:
- Using a npn transistor together with a relay to use them as a digital switch that will open and close the circuit that controls the gate, thanks to the Particle Photon.
- Developing a web app with node.js that will call the Particle functions that open and close previous circuit.
The final result:
And the Photon working:
