Step 1: COMPONENTS REQUIRED Only 4 components required – 1. ESP8266 NODEMCU or WEMOS D1 mini or any esp8266 wifi development board2. RELAY (5V or 6V)3. ULN2003 or UNL2003A (Relay driver IC)4. Jumpers (obviously or else solder it!!) The main structure of the project is that ESP8266 module will receive the signal from the MQTT […]

1 Introduction 1.1 Overview The Arduino microcontroller, a user-friendly yet robust single-board computer, has garnered significant popularity in both hobbyist and professional circles. Being open-source, Arduino boasts affordable hardware and freely available development software. This guide is tailored for students enrolled in ME 2011 or anyone encountering Arduino for the first time. Advanced users can

While simulating an Arduino isn’t a new idea, a recent project by [LRusso] provides an open source JavaScript simulator that runs in your browser. You can try it out live or host it yourself if you prefer. The simulator looks much like the standard IDE, so there isn’t much to learn. You can select from

In this guide, learn to construct a frequency counter device utilizing an Arduino UNO board. This device showcases signal frequency values on a 1602 LCD screen. It is designed specifically to measure the frequency of PWM signals that have a peak voltage of 5V. Hardware Required: Sure, here’s a rephrased list of the components needed

When we first saw [Maarten Tromp]’s article about a “momentary latching switch” for guitar effects pedals, we have to admit to being a bit confused. When it comes to push-button switches, “momentary” and “latching” seem to be at odds with each other, with different mechanisms inside the switch to turn one into the other. What gives?

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to the factory floor whenever the line goes down. Day or night, weekends, vacations, whatever — when it breaks, the process

There was a time when plotters were the pinnacle of computer graphics output. While they aren’t as common as they used to be, there are some advantages to having a plotter. [Symon] wanted a plotter and decided to make one from scratch. Truthfully, he wants to build a CNC machine, so the plotter is just a

Guitarists will do just about anything to get just the right sound out of their setup, including purposely introducing all manner of distortion into the signal. It seems counter-intuitive, but it works, at least when it’s done right. But what exactly is going on with the signal? And is there a way to simulate it?
