The “magic part” of the Raspberry Pi is the 40-pins header, which allows you to connect a wide range of electronic components, like LEDs, buttons, sensors, servos, relays, screens, etc.

More info is available on How to install and use Java 11 and JavaFX 11 on Raspberry Pi boards with ARMv6 processor. The only thing you need to take care of when using a Raspberry Pi Zero of the first generation (a new one was released in November 2021) or older full-size boards, is to use an ARMv6 compatible Java JDK or runtime. You can do exactly the same with the other types of board. In this series, I will be using a Raspberry Pi 4. This board is available with 1, 2, 4 or 8GB of memory. In 2019, the Raspberry Pi 4 was released with a 1.5 GHz 64-bit quad-core ARM processor.
Now different versions of the Raspberry Pi are available, depending on your budget, the connections you need, the processor, the amount of memory, etc. The first version could be connected directly to a television to provide a computer to those who couldn’t afford a monitor. The initial goal of the Raspberry Pi project was to build an inexpensive PC that is affordable for all. This version can replace a full-size desktop or notebook for many use-cases. The latest version, Rasperry Pi 4, has evolved to a powerful machine. The Raspberry Pi isn’t just a small, inexpensive computer-for-everyone.

Go to the Access Management section and create a username and password for the credentials, which we will use in our Java application. You will see the details of your HiveMQ Cloud instance. Once logged in, you will be presented with your HiveMQ MQTT cluster.Ĭlick on the Manage Cluster button. Go to HiveMQ Cloud Sign Up, click on Sign Up Now and create a login. Let’s start with a free HiveMQ Cloud account. In this blog series, I will focus on a few examples with Raspberry Pi and Java.

Still, we require it to keep it up-and-running if we use it as the “central hub” to distribute data.Īnother big advantage of HiveMQ Cloud: It is free to connect up to 100 devices! Even for the most enthusiastic maker, that’s a lot of microcontrollers or computers! You can find example code for many programming languages from HiveMQ. Yes, Mosquitto runs on an inexpensive Raspberry Pi. The biggest advantage of HiveMQ Cloud: There’s no need for an always-on server that one must self-manage. In this series of posts, I am going to take a different approach with an online MQTT-compatible service, HiveMQ Cloud. In this experiment, I created a touchscreen controller to control relays and LED strips and different lights of the drum booth. Introduction: Why Use HiveMQ Cloud MQTT Broker?Ī 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 my son’s drum booth. In this post, Frank explains why he chose HiveMQ Cloud, the cloud-hosted MQTT broker, to send sensor data from Raspberry Pi to it using Java and Pi4J. These blog posts are written by Frank Delporte, the author of a popular book Getting Started with Java on the Raspberry Pi.
Welcome to the three-part blog series MQTT on Raspberry Pi using HiveMQ Cloud.
