Monitoring the temperature of a transformer or electric motor winding involves data acquisition. This project is developed to monitor the temperature of an electric motor and a transformer with high accuracy, incorporating display and alarm facility. This circuit can be installed near a transformer winding or a motor’s location, or it can be attached to […]
Metal oxide semiconductor field effect transistor (MOSFET) is a semiconductor device widely used for switching applications and amplifying electronic signals. While the facility to determine the type and pin configuration of bipolar junction transistors (BJTs) are available in digital multimeters (DMMs) used in the laboratory, most DMMs do not provide such features for MOSFETs. This […]
Panel meters in regulated power supplies are used to display electrical parameters like voltage and current. Presented here is a circuit to display DC voltage and current of power supplies, including DIY-type ones. Circuit and working Circuit diagram of the DC panel meter using Arduino is shown in Fig. 1. The circuit is built around […]
Print Github issues on paper and stack them on your desk. Every time you close an issue and you can literally “bin” it! Things used in this project Hardware components Arduino MKR1000 × 1 Thermal Printer × 1 Software apps and online services Arduino Web Editor Hand tools and fabrication machines 3D Printer (generic) Story […]
This is an image processing based fire detection and extinguisher system using Arduino. It is basically the system is divided into two parts: Fire detection 2. Fire alert and extinguisher In the first part, fire detects using image processing. Here in this project I’m using open CV and python for fire detection. I created a […]

A simple, original and cheap Christmas tree made with LED-illuminated plastic straws that can be controlled over WiFi. Things used in this project Hardware components Arduino MKR1000 × 1 USB-A to Micro-USB Cable × 1 LED (generic) × 12 Resistor 330 ohm × 12 Software apps and online services Arduino Web Editor Arduino IDE Story […]
Light animations are visually appealing and hence widely used for advertising purposes. In this project, we present a MATLAB-based graphical user interface (GUI) approach to control the glowing pattern of a number of light-emitting diodes (LEDs). Use of GUI is advantageous since the user can control illumination patterns while performing other tasks in the PC. […]
Snowman replica that can chat with user to inform them whether outside temperature is safe for outdoor activity or not. Things used in this project Hardware components Arduino MKR1000 × 1 DHT22 Temperature Sensor × 1 Jumper wires (generic) × 1 Software apps and online services Arduino Web Editor Telegram Story Motivation Winter cool is […]
Many times we make projects using Arduino, while working with it we need to connect it with PC to upload program using USB cable. In this tutorial, I’m going to replace this USB cable with a wireless programming shield. This shield is build using a Bluetooth module HC-05. Program Arduino boards without using traditional USB […]
