The green wires going from the relay will be connected to the screws on the back of the button that opens the garage.
Instructables arduino garage door opener.
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.
When the fingerprint scanner detects a match it turns the red led green and the applies 5v to the left prong of the transistor which switches and applies 0v to the positive terminal on the garage door.
Just for two or tree doors.
If you can build this you can build the back door deadbolt version.
Turn your normal garage door smart using this diy project.
Use your multi meter to check the input of your garage door.
If this all looks intimidating try starting out with the numerous tutorials on instructables and www arduino cc.
Using 2 micro controllers 2 boards communicating with a personal protocol it really is over engineered but useful nonetheless.
2 install a separate magnet switch also attention to the polarity when connecting the relay board to the garage opener.
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.
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.
In this project we will be using the power of rfid to tap into your garage door opening system.
This project is much simpler than the rfid deadbolt opener and would be a good one to start with.
If this one is too higher than 5v you will have 2 choices.
1 make a circuit divider with 2 resistors.
Check out this project on.
If you like to tinker with electronics arduino will open up a new world of fun and exciting possibilities.
Our own network enabled garage door opener controlled with an arduino.
The diodes keep the high voltage from damaging the arduino board 3.
Always put the esp8266 gnd to the garage motor operner gnd or common.
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.
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.
Project tutorial by dtbaker.
Welding it must be so as shown in the illustration below.
These wires should remain in the terminals of the garage door.
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.
Garage door opener via mobile phone and rfid.
The diode should be there to help the relay.
A freetronics etherten or other network capable arduino board this is the brains of the operation.
