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
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

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

Home electronics can open up a new dimension in home automation especially when used with an Arduino or Raspberry Pi. There is however a very real danger when using mains electricity, including risk of electricution and danger of electrical fires if the components are not rated correctly. See this guide on risks when working with
