How to Control an Arduino from a Web Page

Remote Control: Interacting with an Arduino via Web Interface

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 […]

Exploring Arduino LED Control using Rotary Encoder

Exploring Arduino: LED Control using Rotary Encoder

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.

Dazzle Your Eyes with a Twinkling LED Symphony: Learn to Create Your Own LED Display

This circuit demonstration showcases a random LED flasher controlling twenty lights. LED flashers and sequencers are commonly employed in decorative lighting applications to produce aesthetically pleasing color patterns. Rather than steadfast illumination, these systems cycle LEDs on and off in either a predetermined sequence or at irregular intervals. The latter approach generates a more dynamic,

Touch Capacitive PCB Light Panel

Create a PCB light panel with touch capacitive technology for managing a NeoPixel LED strip

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

Remote control of a multi-light chandelier with Arduino

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

5x5x5 LED Cube Orientation Independent 3D Display

5x5x5 LED Cube – Orientation Independent 3D Display

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

LED Microcontroller Debug Module

LED Microcontroller Debug Module

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

Voice Activated LED Lighting with Arduino

Voice Activated LED Lighting with Arduino

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
