A silly device that records and replays IR signals (after 10 seconds) from TV remotes as a prank.
The parts required for this project are:
- 1x Arduino Nano (with male header pin strips)
- 1x IR receiver
- 1x IR transmitter
- 1x 1kΩ resistor
- 2x Female header pin strips
- 1x 2 position wire to board mount
- 2x 3 position wire to board mount
- 1x prototyping board (or etch a PCB using the 1.25 scale PDF)
- 1x 4AAA switched battery pack
- Plenty of wire for both the connections on the prototype board as well as the IR reciever/transmitter cables
- Heat shrink tubing
This project uses the Arduino Nano, as such the flashing should be performed as usual via the Arduino IDE.
This project utilizes the Arduino-IRremote library found here.
This should be installed as per the usual processes for adding a library to the Arduino IDE.
The components should be soldered together (using the prototype board) as per the circuit diagram below with one nuance; where the Arduino Nano is placed the female header pin strips should be soldered instead.
To the IR reciever and transmitter, 3 wires should be soldered.
These wires may then be wrapped in heat shrink tubing to make them more aesthetic.
To complete assembly:
- The battery pack may be connected to the 2 position wire to board mount as indicated by the schematic ($U4)
- The IR reciever may be connected to the 3 position wire to board mount as indicated by the schematic ($U3)
- The IR transmitter may be connected to the 3 position wire to board mount as indicated by the schematic ($U2)
- Zip-tie the battery pack to the prototype board.
