# Raspberry PI Garage Door Remote

## Why

Most Raspberry PI Garage Door remote control solutions are complicated and sometimes costly. Here is a simple, low cost alternative.

## How

1. Getting Ready

    * Find a garage door remote that runs on a 3.3v battery. I used a 371LM Liftmaster Remote Control.

    * Program it to your garage door if it isn't already.

    * Remove the PCB from the plastic case and remove the battery.

2. Powering It Up

    * Solder wires to the positive and negative (ground) battery connections.

    * Connect the positive and ground wires to your Raspberry PI. I used PIN 1 (3.3V power) and PIN 6 (Ground)

    * Test your connections by pressing the button on the garage door remote. It should... work.

3. Pressing Buttons

    * Solder a wire to the PCB that will simulate a button press.

    * Connect the button pressing wire to a GPIO on your Raspeberry PI. I used pin 40 (GPIO 21) because it defaults to normally open.

4. Remote Control Web API

    * Compile and run the golang garage-door-remote program. If you used a different wiring scheme than I did, please be sure to change the code!

    * Visit http://raspberrypi:8081/ to press your garage door button programatically.

5. Tasker

    * Put a NFC sticker inside your garage door keypad

    * Program Tasker to recogonize this sticker and GET http://raspberrypi:8081/.

    * Enjoy being able to tap your phone to your garage door keypad and watch as the door opens... instantly.
