“Turn MIDI data into stepper motor music! I was doing my usual, browsing YouTube when I saw some floppy drive music. Having known that floppy drives are controlled by stepper motors, I decided to make my own stepper motor sound generator. I had seen that people had done this before, but every instance had either not shared the code or …

“Remote controlled relays using Bluetooth HC-05, PIC microcontoller and LabVIEW. This project is done on a company requirement which want to change the legacy Switch Control Board to Wireless Controlled Board. As per requirements, Bluetooth module is used which use UART communication. GUI of the Project is developed in LabVIEW in which working is a fun. LabVIEW send the …

“In this tutorial we will learn how servo motors work and how to control servos using Arduino and PCA9685 PWM driver. You can watch the following video or read the written tutorial below. Overview There are many types of servo motors and their main feature is the ability to precisely control the position of their shaft. A servo motor is …

“The IOT123 BRICKS are DIY modular units that can be mashed up with other IOT123 BRICKS, to add functionality to a node or wearable. They are based on the inch square, double-sided protoboards with interconnected through holes. A number of these BRICKS are expected to be on multiple nodes (Master MCUs - ESP8266 or ATTINY84) on a site. The MCU needs …

“Have you ever thought of putting together a laser plotter using a Raspberry Pi CNC Hat? We do precisely this in our project today. Ill introduce you to an XY table, which is the basis of this “printer, which serves both to record and cut certain materials, and involves the whole assembly process in the mechanical part. For our project …

“A friend and I recently worked on creating a device for a Quadriplegic they know to allow him to use his computer. After some research, we decided on a “Sip-n-puff” combined with a joystick to give Allen the ability to move the cursor around the screen a click things. A Sip-n-puff is an input device that takes user input in …

“Below you find a very simple and easy to build device to demonstrate pressure measurements. It might be usable for schools or other STEM related projects, but may also be adapted to be integrated into other devices. While there are several sensor breakouts for pressure measurements available today, I was missing a simple and cheap device to play with these …

“Create a tiny ATtiny85 controller board that drives some NeoPixels and turn it into laser LED light display. Introduction I had a bunch of ATtiny85 chips laying around and reels of NeoPixel strips, so I decided I wanted to make something bright and colourful for my kids…. The full build process is in the video but I have included some …

“My version of a word clock will not feature a 1212 LED-Matrix display. Instead its made with LED strips and only the significant words on the clock can light up. With this method you cant display custom messages, but the whole build wont cost you as much either. This instructable is an almost exact copy of my article, which …

“Dear friends welcome to another Instructable! Today we are going to learn how to put the ESP32 chip into the Deep Sleep mode in order to conserve power and make our projects battery friendly. Have you imagined you project to last on regular AA batteries for almost 5 years? This is possible with the ESP32 chip. The ESP32 chip is …
