This sketch demonstrates Internet-based remote communication using a companion ‘bridge’ program running on the attached host which sends and receives messages via an online MQTT server. This allows connecting one Arduino to another over arbitrary distances, which we can use as a starting point for building collaborative telepresence. This example is configured to provide for […]

Upon acquiring my initial Arduino board, my immediate aspiration was to administer it through a web interface. However, lacking an Ethernet shield initially, I deferred the idea. Recently, spurred by curiosity, I procured a shield from Amazon to explore the possibilities. The foremost step entailed drafting a basic sketch capable of rendering a web page

Introduction Hello everyone, welcome back to Techatronic. Within this article, we’ll be creating an Arduino LED project using a rotary encoder and a 16×2 LCD module. To ensure ease of understanding, we’ve included circuit diagrams and detailed connection descriptions for each setup. The rotary encoder comprises 5 pins, two for power and three for data.

In this guide, we will illustrate the process of crafting a touch capacitive PCB with an ATMega328P IC, designed to oversee Neo-Pixel LED strips. Our PCB boasts versatile capabilities, encompassing music-reactive, random animation, and RGB control modes. Building on our prior exploration of touch capacitive technology in the touch capacitive piano tutorial, this project focuses
Story: It all began with a seemingly simple intention – replacing the bulbs in the chandelier adorning my bedroom. As you can observe in the accompanying image, the chandelier boasts an elegant design. Yet, a minor predicament emerged. To begin with, the fixture comprises a total of 15 illuminations and was initially crafted to accommodate

Introduction Our project, in one sentence, is an orientation independent 3D LED display. We were inspired by various videos on youtube of similar cubes but also by the idea of creating an interactive 3-dimensional display. We built a 5x5x5 LED cube display and controller board which interfaced the cube to a Mega32 microcontroller. We

When it comes to debugging a microcontroller circuit, there aren’t a lot of simple options. Since a microcontroller circuit might have multiple things going on at the same time, measuring voltages with a DMM isn’t an option. Using an computerized In-Circuit-Debugger solution is expensive and elaborate, and time-consuming to set up. People often resort to

This project is an extension to the Speech Recognition with Arduino by leandro4b (http://www.instructables.com/id/Speech-Recognition…). However, instead of using 3 separate colored LEDs, I used a multicolor 4-channel RGBW LED Emitter. I had the opportunity of working at LED Engin last summer, which is why I was able to use the high power 4-die RGBW emitter

The first time I saw a POV (Persistence Of Vision) display was on a show called FAQ on TV. The POV display consisted of an oscillating shaft with 6 LED’s mounted on the end of the shaft. Since then I have always wanted to make one myself, I tried making one about 2 months ago

I’m currently in the process of making a Halloween contraption that has a few components that are worth documenting. The Huge Arduino Animatronic LED Eyeball is one of them. Background Most animatronic eyeball projects that I found were more or less life-size. They were usually ping pong balls or dolls eyes or 3-D printed. I
