Java and Arduino: Serial Communication

Java and Arduino: Serial Communication

Before we started using Firmata and Firmata4j in the EECS 1021 class, Richard Robinson and I put together lab activities that used the Fazecast jSerialComm library paired with customized Arduino serial code.

The approach is summarized in three videos:

Video 1: The Plan for Sending Data to an Arduino

We need to send information, in this case a countdown sequence, to an Arduino from a Java program on a PC (macOS, Windows, etc.). We're assuming that you've already got a C++ program running on the Arduino (or similar) microcontroller board. Let's plan out an approach to a thread-based Java program that sends a byte of information at a time at regular (1 second) intervals.

Part 1 of sending data to an Arduino from Java using jSerialComm

Video 2: The Implementation for sending data to the Arduino from Java

Here we go through the actual implementation for how we send data from a Java program to an Arduino using the jSerialComm library.

Second part: implementation.

Video 3: Receiving Arduino data in Java

So, you want to send a signal to your Java program from an Arduino. How do you do that? Here we go over a ``simple'' example.
