Raspberry Pi Garage Door Opener with GaragePi

Introduction When I was little, I used to push the garage door button from inside the garage and then run out the garage while it's closing... carefully jumping over the sensor so I don't trip the safety mechanism. It was easy back then and a little fun. But nowadays, not so much. There are times when I wish I had a way to close (and open) the garage door remotely and preferably with something I always have ...

Expanding the Raspberry Pi with PiFace and Pi Rack

The marvellous Raspberry Pi, essentially a cheap, small PC, is a great device for education or home projects like media streaming. Out of the box though, it is not ideal for controlling other devices other than by USB or ethernet. What if you wanted to to use it to operate a switch under program control? You can use the GPIO (General Purpose IO) header, but it is a considerable step up in terms of the elect ...

Aaron’s piHouse Monitor

ntroduction I have been using microcontrollers for a long time now.  I started in college as part of the program and have never stopped.  Professionally, educationally, hobby, I've done projects of all types. Recently I decided to try something with a Raspberry Pi.  It is the next step up, basically being a little computer.  This was so I could play with Linux again (it's been years) and do something with a ...

Home Automation with Raspberry Pi

The Surveillance System this year I planned to travel with my family to China for a few weeks, so we had to leave alone our house. While being on vacation, I wanted to check sometimes if everything was alright at home. So I decided to install two more cameras and connect them to the webserver of my home automation system. I had one camera attached already before and I wrote about it here. Both cameras I pla ...

Raspberry Pi – homemade level converter for serial communication rs232 3.3 volts to 5 volts TTL for AVR microcontroller

I found that the Raspberry Pi serial interface rs232, described in a older post by myself, was too bulky. Pi and AVR should be connected through a less amount of wires. So I’ve searched the best hints to solder a cheap and uncomplicated level converter, that can directly be connected between the GPIO of the Pi and the rx/tx pins of the microcontroller. On the German website http://www.elektronik-kompendium. ...

Project Coffee: Es(pi)resso Machine

ome time ago, I embarked on a project to control my Gaggia Classic Espresso machine with a Raspberry Pi. Obviously, you can buy a fully automatic “bean to cup” machine… but where’s the fun in that! This project started out with the simple idea of improving the temperature stability, and grew into a more elaborate controller with an LCD screen, water level sensing and pump control. This is an attempt to docu ...

Home Weather Display

In this project, we use a Grove DHT (Digital Humidity and Temperature) sensor as a Raspberry Pi temperature sensor.  This project uses a Grove OLED display, connected to the Raspberry Pi, to show the temperature and humidity.  You can use this project as designed: a simple weather station for your home. You can also use this example project as a basis for your own project.  The project shows how to use a th ...
