Then wire pin 6 gnd to the gnd on the relay.
Raspberry pi zero w garage door opener.
Welcome to the 13th raspberry pi tutorial.
Same kind of setup but using an extra wireless remote.
Then another wire for the to a ground on the pi.
Wire pin 2 5v on the pi to the vcc pin on the relay.
First step is to solder a gpio header to your pi zero assuming it doesn t.
So you can look up resistors on wikipedia but what do they mean to us.
It controls the door.
Setting up software raspberry pi.
I wasn t willing to kill my only remote.
Thought i d do something a little different today and just show a demo in the video below and write out the steps to the actual project here and on github.
Wiring 4 ch relay to raspberry pi.
Raspberry pi garage door opener with garagepi by chase chou.
Introduction to the raspberry pi gpio.
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.
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.
Required for this project is a raspberry pi zero w or raspberry pi 3 model b other models like the raspberry pi 3 model a may also work compatible power supply button 5 volt relay switch solder and soldering gun cables wires circuit board a basic understanding of the http hypertext transfer protocol the pythonprogramming language and the linuxoperating system.
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.
This was my first hardware project and instructable ever and i m sure.
Along the way i learnt about webiopi to check my gpio over a webpage.
While this has been done before i thought i d post my solution.
The main interface we will be using with the raspberry pi is the gpio.
Raspberry pi garage door opener.
Raspberry pi garage door opener.
This instructable explains how i setup a raspberry pi to open my garage door using a smarthphone.
This model is necessary as it has wireless support while the raspberry pi zero does not.
Raspberry pi zero garage door opener hardware step 1.
It proved to anyway use the same kind of electrical setup for the command part.
There are many different combinations that will work i tried to be clear but.
Then wire the relay to the garage door opener.
