Introduction In the realm of telecommunication and computer networks, the application of Dual Tone Multi-Frequency (DTMF) technology has extended beyond traditional telephony into diverse fields, including industrial automation and control systems. One intriguing application of DTMF technology is in the speed regulation of DC motors. This project, titled “Speed Regulation of DC Motor Using DTMF
The Raspberry Pi 3B+ (as well as all other Raspberry Pi models currently available) comes equipped with built-in WiFi functionality. The “wlan0” interface serves as the default connection gateway alongside Ethernet, yet it lacks the capability to enter “monitoring mode.” In this guide, we’ll demonstrate the steps to ensure that a separate network adapter is

There are some great hackable devices in the SONOFF range such as the original SONOFF switches, the Slampher and the SONOFF Luxury wall plate which is the subject of this instructable. These devices are based around the ESP8266 or ESP8285 WifFi modules and are easily hackable. I’ll only cover here how to convert a wall

OK So my third Instructable and here we’re dealing with another Sonoff device, the original Sonoff WiFi smart switch. Theses devices are again based around the ESP8266 and are easily hacked. The devices can switch up to 10A @ 240V so are ideal for switching lights, TV’s, games consoles etc. Please don’t try running a

Some time ago, I tried to make an “Instructables Hit Counter” using the Instructables API, and an Arduino Uno with a wired network shield. However, with the limited RAM of the Arduino Uno, I was unable to get the system to work. A while ago, I noticed a similar project done by diytronics using a NodeMCU. This was just

An Embedded Machine learning-based project was used to detect fire using the inbuilt colour sensor. Description It’s an embedded machine learning-based project used to predict a fire in Arduino nano ble 33 sense with the help of the inbuilt color sensor attached to the board and if the fire has been detected a buzzer is

This utility GUI application is a tool for visualizing the content of multiple data streams passed as short numeric messages back and forth across the network via a MQTT server. It supports opening an authenticated connection to the server, subscribing to a class of messages in order to receive them, viewing message traffic, and plotting
Arduino MQTT Plotter (PyQt5) Continue Reading
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

As usual, this Halloween I decided to create a project related to the season. Using Prusa I3 and Thingiverse, I printed a Halloween decoration where the color is controlled remotely through the Blynk project. The Blynk project lets you create a mobile or tablet app that interacts with controllers like the Arduino Uno or the

It is a truth universally acknowledged that a single cat in possession of good fortune must be in want of a laser toy. As with single gentlemen in want of future wives, some precautions must be observed. But is that not true of anything really worth having? If you do have concerns about pets and
