HiveMQ Cloud, part 2 - Using MQTT and Raspberry Pi to Visualize Sensor Data on a TilesFX Dashboard
In the previous post we started our discovery of HiveMQ Cloud with Java on the Raspberry Pi. We created an application to send measurements of various sensors to the HiveMQ Cloud MQTT broker. Using an online websocket client we verified the transition of the messages, and could see the data being published to this online message queue.
HiveMQ Cloud, part 1 - MQTT on Raspberry Pi, Send Sensor Data to HiveMQ Cloud with Java and Pi4J
A few years ago I did my first experiments with an MQTT server (Mosquitto) running on a Raspberry Pi to connect an Arduino and Raspberry Pi for the drumbooth of my son. The full process is described in my book “Getting Started with Java on the Raspberry Pi”.
JavaFX running in kiosk mode on the Raspberry Pi
The Raspberry Pi in combination with an inexpensive touch screen, makes a perfect controller for a machine or game console. Let’s see how we can use Java and JavaFX to build a test application which also communicates with the pins of the Raspberry Pi to control a LED. We have done something before already in the post “Light Up your Christmas Tree with Java and Raspberry Pi”, so what’s new?
Device monitoring tool with JavaFX, FXGL and Mosquitto
In a previous post “Getting Started with FXGL Game Development” we already have taken a look at the FXGL game development framework developed by Almas Baimagambetov.
JVM Advent 2020 - Light up your Christmas lights with Java and Raspberry Pi

JFXDays presentation - Having fun with Java and JavaFX on the Raspberry Pi
Today I could give my talk “Having fun with Java and JavaFX on the Raspberry Pi” at the JFXDays. Normally this event takes place in Zurich, but this year also went virtual because… well because of 2020…
Building native applications for all PC and mobile platforms from a single JavaFX project with Gluon Mobile and GitHub Actions
The post “Starting a JavaFX Project with Gluon Tools” shows you how to start a Gluon Mobile Multiview project with a few clicks in IntelliJ IDEA thanks to the “Gluon plugin”.
Starting a JavaFX Project with Gluon Tools
On foojay.io you can already find two posts by Carl Dea to get you started with JavaFX:
Devoxx Ukraine presentation - Having fun with Java and JavaFX on the Raspberry Pi
Today I had my first Devoxx talk, after my Java virtual talk a few weeks ago at the “Oracle Groundbreakers APAC Virtual Tour 2020” conference (21/10)! The event in Ukraine also went virtual which gave me the opportunity to share my love for Java, JavaFX and the Raspberry Pi again.
