Raspberry Pi Antics (Garage Door Opener) « Scott The Robot. So, not long ago I received a Raspberry Pi in the mail.
Yep, that’s the ultra-coveted, ultra-backordered, ultra-low power, ultra-small, ultra-awesome single-board-computer that only costs $35 (give or take). I had it kicking around for a few weeks running Debian before I really had a solid idea of what I should do with it, which turned into an exercise in home automation. I plan to design a home automation system with my electrical-engineering-major roommate come September. Essentially, this exercise serves as a proof of concept which demonstrates the reliability of the Arduino-Server communication as well as the viability of the Raspberry Pi as a platform for running the home automation software. Overview Anyway, the abstract design for our system will be a chain of microcontroller nodes all connected back to a server, which monitors the system, provides a web interface, and automates.
I will spoil the fun and say the project was successful. Design Making it Garage-Proof Installation. 2-Channel 5V Relay Module for Arduino DSP AVR PIC ARM SainSmart. We accept payment through PaypalPayPal is a safer, easier way to pay.

There’s something exciting about crossing the boundary between the abstract world of software and the physical ‘real world’, and a relay driven from a GPIO pin seemed like a good example of this.
Although a simple project, I still learned some new things about the Raspberry Pi while doing it. There are only four components required, and the cost for these is around 70p, so it would be a good candidate for a classroom exercise. Even a cheap relay like the Omron G5LA-1 5DC can switch loads of 10A at 240V. A word of caution: don’t tinker with mains voltages unless you’re really (really) sure about what you’re doing. A mechanical relay allows a safe learning environment, since you can switch any load with it (e.g. a 9V DC battery/bulb circuit for testing), and the concept of a mechanical switch is very easy to grasp. The Circuit There are four components to this circuit.
A relay will often have 3 significant voltage/current ratings specified; coil, AC load, and DC load. The C Code Alternative. Nodejitsu/forever. Hacking My Garage With A Raspberry Pi - It's Brent. Several months ago our Craftsman garage door openers stopped responding to our remotes.
I tried everything I could think of to fix this problem, short of buying anything new. Garage door opener parts are expensive, to the point buying new openers is a better option. After much research I found out that RF interference was the issue. No new remote or logic board was going to solve the issue, even getting new openers wouldn’t solve the issue. By knowing the wall switches work by simply closing the circuit I set out for a wireless solution that we could control from our iPhones. Don’t forget (assuming you don’t have these lying around): After getting the parts in I wrote a quick node.js app that serves a single page and also has a 2 backend requests to open each garage. . $ sudo apt-get install node ... $ sudo npm install forever -g The only issue I came across was that the relay I bought turned on when firing low, and off when high. As far as wiring goes, I have 2 sets of door switches.
