Introduction: Iphone PIR Motion Detect Shutter Modification
Step 1: How To
- cheap iphone/android shutter from ebay ($2)
- basic NPN transistor (BC182)
- 1K resistor
- Arduino (nano)
Disassemble the shutter.
Solder two wires on the shutter pcb battery connections
Solder another two wires to the shutter button (key1 for android, key2 for iphone)
Wire the PIR sensor to the arduino:
PIR sensor GND to the arduino GND
PIR sensor 5v to the arduino 5v
PIR sensor data to the arduino D2 pin
Wire the shutter to the arduino:
Put an 1K resistor between arduino D4 pin and the transistor base.
Connect the shutter button wires to the transistor Collector and Emitter pins. (if not work, replace C E wires)
The shutter work from 3v, so connect the shutter positive to the arduino 3v3 pin,
and shutter GND to the arduino GND.
Check the pictures above
Upload the arduino code. (arduino code in video description)
Its a very basic code, almost same the arduino button example.
Pair the shutter to the phone in the Settings/Bluetooth option.
You can download from the App Store spy camera app with turned off screen record...
