Story

Using particle argons alongside IFTTT we were able to have an alert sent to our phone to tell us that a door had been opened. The alarm works using three different breadboard circuits all communicating with one another and with IFTTT to send a notification when the door it is connected to is opened thus creating a simple, cheap and effective security system.

The idea came to us after hearing about all the safety concerns on campus and deciding we needed a cheap alternative to a home security system.

How it works is using three breadboard circuits each with their own task. The first being the laser emitting circuit and using a laser emitting diode will function with the laser receiving circuit, consisting of a photo resistor, and led which will function with the third circuit, the alarm circuit which will then communicate with IFTTT to import the data it receives into a Google spreadsheet and to send the notification to the cellular device.

Laser Emitting Circuit

Attach particle argon device to breadboard and connect to power source
Attach laser emitter to other breadboard
Plug jumper wire to a digital write pin of the particle argon device and jump to the positive power rail
Jump wire from the positive power rail to one of the outside pins of the laser emitter
Plug jumper wire to the ground of the particle argon device and connect to the negative power rail
Jump wire from the negative power rail to the middle pin of the laser emitter

Laser Receiving Circuit

Connect Particle Argon to breadboard and connect it to its power source
Attach laser receiver to other breadboard
Attach jumper wire to a digital write pin on the particle Argon device and jump this to the positive power rail of the breadboard
Jump wire that is coming from the positive power rail to one of the outside pins of the laser receiver
Plug jumper wire to the ground of the particle argon device and connect it to the negative power rail of the breadboard
Jump wire from the negative power rail to the middle pin of the laser receiver

Data Acquisition Circuit

Get breadboard
Setup Argon to Particle app
Place now connected Argon on breadboard making sure the Argon device is securely fashioned to breadboard
