If you can build this you can build the back door deadbolt version.
Instructables arduino garage door opener.
Turn your normal garage door smart using this diy project.
The diode should be there to help the relay.
I will show you how to build it and control it using home assistant over mqtt and have the ability to remotely open and close your garage door i will be using an esp8266 board called wem.
Arduino rfid garage door opener.
Always put the esp8266 gnd to the garage motor operner gnd or common.
Project tutorial by dtbaker.
Welding it must be so as shown in the illustration below.
Use your multi meter to check the input of your garage door.
These wires should remain in the terminals of the garage door.
Diy smart garage door opener home assistant integration.
Garage door opener via mobile phone and rfid.
The port nº 5 of the arduino uno activates the central button door 2 of ios app open your garage and the port nº 4 of the arduino uno the right button door 3.
A freetronics etherten or other network capable arduino board this is the brains of the operation.
Check out this project on.
This project is much simpler than the rfid deadbolt opener and would be a good one to start with.
Our own network enabled garage door opener controlled with an arduino.
The green wires going from the relay will be connected to the screws on the back of the button that opens the garage.
The diodes keep the high voltage from damaging the arduino board 3.
1 make a circuit divider with 2 resistors.
If this one is too higher than 5v you will have 2 choices.
In this project we will be using the power of rfid to tap into your garage door opening system.
The wires from the garage button mounted on the wall should be 15v if not message me and ill help you may need to change wiring and the program a bit.
2 install a separate magnet switch also attention to the polarity when connecting the relay board to the garage opener.
Just for two or tree doors.
The arduino will switch the transistor i used a bc338 that i had laying around but any 5v npn general purpose will probably do and the transistor will switch the relay.
We are going to bridge a connection in the opener switch via a robotgeek relay board initiating the door opening as if you had pressed the button.
It hosts the web page you connect to when you want to open the door and triggers the garage door opener via the relay when the correct password is entered.
That version just has more outputs and a longer sketch.
If this all looks intimidating try starting out with the numerous tutorials on instructables and www arduino cc.
