In this tutorial, I want to show you how you can read the temperature, humidity, and pressure from a BME280 Sensor.

The Raspberry Pi allows us to do a lot of electronic projects without having to wait for ordered components… or even buy them at all… by using virtual components.

Today, I want to show a way to play with a potentiometer. A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

In this article we present you with another great example of Java on Raspberry Pi. It shows how to create a Micronaut Velocity demo using an 8×8 LED matrix display.

Both on hardware as software level, you have different possible approaches, but the result is the same… a fun project to learn new software technologies and getting introduced into electronics.

The “Hello World” version of electronics programming is a blinking LED. But, in this post, we will go a few steps further and control 8 LEDs inside a number display.

Igor De Souza, Dublin based Principal Big Data Consultant at Oracle, set up an interesting experiment in which he combines a LED number display with the Raspberry Pi and Quarkus.

Thanks to Twitter and LinkedIn, I’ve been in touch with several developers who are doing cool Java stuff on the Raspberry Pi.

Here I want to share those projects with you, as they can be an inspiration for all of us to get started with Java development on the Raspberry Pi!
