Introduction
This post will show you how I connected my garage door to an arduino with a bluetooth module (HC-05) to control the door with a smartphone
Hardware
We need a few things:
- Arduino
- HC-05 bluetooth module
- Arduino 5v relay
- Automated door (controlled by a button)
Software
Here we have 2 components, an Android app which will connect to the arduino.
The arduino code to control a relay which will simulate the button pulse.
Android App
cumal/MyDoor: Source code for myDoor project. Android & Arduino (github.com)
I created an Android app which connects to the Arduino and send messages. This app is not published in Play Store, so you will have to compile it with Android Studio
Arduino Code
cumal/MyDoor_Arduino: Arduino code for myDoor app (github.com)
Install this software into an arduino, in my case I have running it in an arduino nano. The software reads the bluetooth received string and if match with the key, activates the relay to simulate a push.
