A lot of Arduino projects are meant to always be attached to a PC, transferring data back and forth between the Arduino and the PC. That's why Firmata, a program that sits on the Arduino and allows a program on your PC to remotely read from sensors and buttons and transmit to things like speakers […]
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 […]
In the EECS 1021 class here at York University the students learning about object oriented programming in an engineering that uses sensors and actuators. We use Arduino devices that host a special pre-made firmware called Firmata to do this in order to unburden the students from the C++ coding that would otherwise be required on […]
Heard about Virtual Programming Lab (VPL) and eClass at York and want to "kick the tires" a little? If you haven't already, VPL is a plugin for Moodle (eClass at YorkU) that allows instructors to create interactive programming activities for students. Here is some introductory material. [this may need an update after the update in […]
In my EECS 1021 class, in which we connect Java programs on a Mac or Windows machine with programs running on an Arduino-compatible board, we generally use Firmata. When combined with a library like Firmata4j (Java) or pyFirmata (Python), or Arduino-Octave (Matlab), Firmata provides an easy-to-use pathway for this to happen. It is, however, a […]
Arduino devices are commonplace in Engineering programs. Even if the profs don't use them, the students do. In Engineering programs, we often need to set up sensor monitoring or motor control systems. If students haven't worked with these in the first through third years of their programs, they are likely to encounter them in the […]
In our first year programming class for engineering students, EECS 1021, we're using modern features like jShell and var. Unfortunately, the OS that our VPL instance sits on came with an older version of Java, so we've had to modify our scripts to point to the Java 17 JDK. If you get an error like […]
Firmata is a set of Arduino projects that are aimed at helping solve a particular class of problems with embedded devices: having a main computer send and receive data from an Arduino, typically in a simple control or data-logging application. This is similar to how people use the Arduino support for Matlab. In Java we […]
Virtual Programming Lab is a plugin for Moodle (eClass at YorkU) that permits interactive programming assignments to be made for students. There are some really good examples at Smith College on how to set it up with Python and a few with Java and C. I've posted, on YouTube, an example of how to […]
