Garage door opener using a raspberry pi step 1.
Open a garage door with a raspberry pi.
Raspberry pi garage door opener step 1.
The operation of the motor works as follows.
Build a raspberry pi door window sensor with reed relais.
The relay should be wired in the normally open position so that when activated the circuit will close and the garage door will open close.
Setup wifi via the command line.
My garage door remote uses the cr2032 battery which is 3 3v and coincidentally the raspberry pi also has a 3v terminal which is right next to the 5v plug.
So you basically remove the battery on the remote and connect the on the battery compartment on the remote to the 3v on the pi.
Connect 2 wires from each garage door opener switch.
Learn programming c javascript jquery the mean stack mongo express angular and node and excel.
Then wire pin 6 gnd to the gnd on the relay.
Learning programming made easy.
The software relies on python flask and wiringpi gpio python module.
I use a raspberry pi computer to control opening and closing of the door.
Install and optimize rasbian for our purposes.
As a programmer i like to reuse tutorials or already production level code.
The next step is to setup your wifi from the command line.
Demo and tutorial on how to control your garage door from your phone using an esp8266 module nodemcu and raspberry pi.
All activity is monitored and logged using the raspberry pi.
Then wire the relay to the garage door opener.
This will allow us.
Wire pin 2 5v on the pi to the vcc pin on the relay.
A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated.
The two wires from the raspberry pi go to the magnetic switch with half of the switch mounted to the center channel and the other half mounted to the carriage slide with the two sides lined up with the garage door closed.
Now that the relay is connected to the pins it s time to setup the os and software we will use to.
Conection to garage door openers.
In practice a simpler and cheaper device such as an ardunio microcontroller would work.
With a magnet attached to the garage door the pi relies on two magnetic reed switches to check the garage door s status.
However i had a raspberry pi lying around with no use so i wanted to put it to work.
In addition to a surveillance camera and motion sensors information about open windows and doors is also of interest to a self built surveillance system.
