Drumbooth controller with Raspberry Pi and JavaFX
Based on multiple examples from my book “Getting started with Java on Raspberry Pi”, I created a touchscreen controller for the drum booth of my son. Combined with relays boards and an Arduino this allows to control LED strips and different lights with a touch screen interface. There is also a web server included so we […]
Raspberry Pi and SPI 8×8 LED matrix example with Java and Pi4j
While looking for a cheap and nice component to demonstrate the use of SPI (Serial Peripheral Interface) I found out this 8×8 matrix LED display on a board with a MAX7219 chip is the perfect piece of hardware!
OpenWeatherMap forecast on LCD with Raspberry Pi, Java and Pi4J
Pi4J contains helper methods to minimize the work needed to use certain hardware modules on the Pi with Java. As an example, we will be using “GpioLcdDisplay” to control an LCD with 2 rows of 16 characters. After requesting the weather forecast from a public website, we will visualize this on the LCD display.
Controlling a LED number display with JavaFX and Python on Raspberry Pi
In my book I explain the use of bits and bytes by using a shift register SN74HC595 IC and 5101AS LED number display.
Controlling Arduino with Mosquitto and JavaFX on Raspberry Pi
One of the example applications in my book “Getting started with Java on the Raspberry Pi” combines a JavaFX application with Mosquitto on the Raspberry Pi to control a LED strip with an Arduino. All wireless and independent of each other as the Mosquitto-queue is dealing with exchange commands between all applications.
