In this project, we will build a water spraying intruder alarm using a Lightblue Bean (a BLE enabled Arduino micro controller). After spraying the intruder, the Lightblue Bean will trigger a nearby computer to take a picture, and upload it to Twitter! We will also be able to remotely arm or disarm the motion detector by sending a message to the Bean through Twitter.


Step 1: Parts and tools

You will need:

Lightblue Bean
Super Soaker Thunderstorm motorized water gun
PIR sensor
MOSFET
10K Ohm resistors x 2
1N4001 diode
4xAA battery holder
Wire
Tape
An empty toilet paper roll

Tools:

Soldering iron
Screw driver
Drill/dremel tool
Software:

Node-RED
Python
