The Raspberry Pi Pico W web interface controls the garage door


Raspberry Pi Pico W projects are finally here and this one, created by Core Electronics, adds to the plethora of DIY home automation projects. Using the new Raspberry Pi Pico W microcontroller, the team is able to control a garage door via Wi-Fi using a custom web server running on the Pico W.

The Pico W is wired to the garage door controller via an interface circuit with an N-channel MOSFET capable of working with the 12V controller. This interface is able to open, close and stop the door on command. The Raspberry Pi Pico W takes care of hosting a web server and a simple web page with three buttons, one to launch each of these commands. This allows the garage door to be controlled from any device on the network, including PCs, tablets and even from a smartphone.

Core Electronics has tons of cool projects on the Basic electronics website using not only Raspberry Pi projects but also various microelectronics like Arduino and more. Some past examples we appreciate include this Pi-powered system that can identify birds via the audio input as well as this impressive weather display which also serves as a rain radar.

In the project breakdown, Michael explains that the Pico W is the main engine of the project which is connected to a Makerverse Protoboard with a Pico breakout. A few additional components are needed, such as resistors, transistors, and a 5V DC-DC converter. The full parts list is available in the project’s build guide. The Pico is powered by the DC-DC converter and uses three open-drain outputs to drive the garage door motor inputs.

Software-wise, it’s programmed using a custom MicroPython script that’s open-source and available to anyone who wants to check it out in its entirety. It creates the web server that handles all button inputs, sending the appropriate signal to the garage door to respond as desired. It should also be noted that this project is a bit of a security issue as anyone on the network can access the control panel.

This project would work well in tandem with Jeff Geerling’s Pico W powered garage door sensor, which is designed to detect whether his garage door is open or not and automatically notify the user if the door is mistakenly left open. Project details for this development can be found at GitHub.
