This command-line Python script transmits MQTT messages based on events from a MIDI input device such as the Akai MPD218 Drum Pad Controller. This can be used as a platform for remote control of one or multiple embedded devices. The MQTT and MIDI configuration must be customized by editing variables with the script before this can

I have a FlashForge Finder 3D printer that did not come with a heated bed. The factory build plate is also somewhat limiting in what kind of build surfaces you can use. I finally decided it was time to resolve those issues and added a heated bed. For my project, I needed to convert the

Some of the exercise packages include several utility and test programs. These are all standalone scripts using Python 3 and a few additional packages as described in Python 3 Installation. The following scripts may be browsed in the Python MIDI tools directory on the course site. list_MIDI_ports.py Command-line test program for identifying available MIDI ports by printing a

This utility GUI application is a tool for debugging programs using a remote MQTT server. It can show messages on multiple topics and publish text-based messages on a single topic. The application is provided all in one file and can be be directly downloaded from qt_mqtt_monitor.py. The following sections have both documentation and the full code.

This tutorial shows how to move two stepper motors so they will synchronously arrive at defined destination point. There are many sophisticated solutions for doing this such as GRBL or Marlin. Using an Arduino, there are also dedicated “Multi Stepper” libraries that can support you. However, we will use a more basic approach here making it as easy as possible

In this Instructable I will show you how I made my PCB Farkle Game! Farkle, also known as 10000, Zilch, 6 Dice, and Ten Thousand, is a fun and challenging dice game with multiple variations and scoring options. I first got the inspiration from my twin brother, Sunyecz06’s Liar’s Dice PCB game in which he utilized a

This PyQt5-Enabled Arduino MQTT GUI connects an Arduino sketch to a remote MQTT server over the network. It communicates with the Arduino using the serial port, relaying lines of text to and from the MQTT server. This can be used as a platform for remote Arduino to Arduino collaboration. The application is provided all in

This collection of short Arduino sketches introduces a variety of programming concepts. The comments are minimal as these are intended to be starting points for explanation. blink // 1. blink the onboard Arduino LED on pin 13. // 2. demonstrate setup(), loop() // 3. demonstrate pinMode(), digitalWrite(), delay() void setup() { pinMode(13, OUTPUT); } void

N.B. this is new and still being tested. This sketch demonstrates an example of ultrasonic range sensor data processing using a combination of signal filters and a classification tree. The classifier code was generated using the Python script classify_gen.py on recorded and labeled training data. The underlying classification tree was automatically generated using the Python scikit-learn library. For more

In this Instructable, my twin brother, Sunyecz06, and I will show you how to make a 7-segment NeoPixel Clock with Countdown Timer. The inspiration for this project began with our parents and their fitness room. While they have an older digital clock in the room, it has no functionality other than telling the time. And oftentimes,
