Controlling an LCD Display with Spring and Thymeleaf on the Raspberry Pi
Igor De Souza shares on his blog a lot fun and inspirational experiments with Java on Raspberry Pi. Some of those were already shared here on Foojay.io.
This time we want to highlight his work which combines a web app made with Spring and Thymeleaf, to control an LCD display connected to a Raspberry PI.

Vert.x Example on the Raspberry Pi with a Virtual Potentiometer
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.

Electronics & Micronaut Velocity with Raspberry Pi
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.

Electronics & Quarkus Qute on Raspberry Pi
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.
