ESP8266 WiFi Garage Door Opener - Render


This is a bit different then my other “Smart Home” projects since it uses an ESP8266-12F to host a standalone web server. That means you don’t need to install any of that fancy stuff like HAP-NodeJS or a MQTT Broker. Using the HC-SR04 Sonar Range Finder it can detect how far away your garage door is, or if it doesn’t detect it at all to determine whether it is open or closed. There is a Thermistor connected with a Resistor to make a voltage divider to calculate the temperature. During startup the ESP connects to your network and will get your local time if your network has internet and you set the proper timezone in the Arduino Sketch.

ESP8266 WiFi Garage Door Opener - FrontTo power it there are a couple of options. If you are using a 5V Power Supply then all you will be needing is the LM1117 3.3V Linear Voltage Regulator to step down the voltage for the ESP8266, this is the most efficient option in this build. If you don’t have a 5V Power Supply you can use anything from about 6V to 12V with the addition of the LM7805 5V Linear Regulator, my design allows for both options with a jumper to disable the 5V Regulator if required.

Then simply enter the address that can be configured in the Arduino Sketch, mine was garage-home.local and the web page with the controller will show up. everything up with some and some . You will also need a variety of Electrolytic Capacitors, Ceramic Capacitors, LEDS, Resistors, Header Pins, Transistors, etc. that some people might have already on hand or salvaged from some old electronics. You can download my model from Thingiverse and I may design a board in Eagle if there is enough interest for those who either etch your own boards, or would like to just send it away to a board shop to get made by there preferred board manufacturer.

ESP8266 Garage Door Opener Web Server PageNow if everything went well you should be able to open up any web browser on your network and enter the address that was set up during programming, by default it is set to garage-home.local. A controller should show up on a webpage displaying things like run time, temperature, and door status. Here is where you also setup the threshold distance for the HC-SR04 Sonar Range Finder to calibrate the distances. Once everything is tuned all you have to do is push the large open / close button on the remote and your door should operate over WiFi.

3D Print GLOWING ColorFabb XT PLA Filament on PrintrBot

Difficulty: Star LitStar LitStar UnlitStar UnlitStar Unlit (2/5)

Glow in The Dark Peace and Love Heart

It is a mesmerizing video to watch… I use the PrintrBot Simple to 3D print glow in the dark ColorFabb XT PLA Filament. Excuse the quality as this video was shot in complete darkness, and brightened up in post processing.

We used the silicone heated bed set to 65°C and an Extra Wide Roll of Blue Painters Tape for good bed adhesion. My hot end is heated pretty high for PLA, all the way up to 235°C. You might have luck with a little lower temperature but higher definitely will require more heat than normal for PLA.
