We are all familiar with how notice boards in schools, offices, colleges and railway platforms look like. But have you ever wondered how they work and how you can make such a board by yourself? So, today we are going...
Today, we are going to make an ‘all-in-one’ measurement device/instrument, which consists of a digital inclinometer, compass and protractor. It also includes a health monitoring system that can provide data about temperature, oxygen levels and heartbeat. All these features come...
This article describes the procedure to set up Arduino as a slave device, which gets all control signals from Raspberry Pi running a Python program. The program presented here provides simple steps to interface Raspberry Pi and Arduino. Arduino...
Parents often worry about their children when they are away from them. Have they safely reached school? Are they alone at home? Or are they at the playground with friends? - these are some of the questions that bothers...
Presented here is a motion-sensor-based security system using Cayenne and Arduino Uno. Cayenne is the simplest and easiest platform for the Internet of Things (IoT) systems. It allows you to connect regular boards like Raspberry Pi, Arduino and LoRa,...
What if you are out of your home (and/or in another country) and suddenly realise that you have forgotten to turn off the geyser, lights and other electrical appliances? This costly mistake can increase the electricity bill as well...
The entire project is completely automated and available as open-source Thanks to advanced computational methods, 3D scanning can be used to create real-life, three-dimensional computer models of almost any object. To do so, one would need good programming skills along...
This project is based on Arduino Uno and Processing software for monitoring temperature and sending voice alerts. Processing is an open source IDE that can be used to visualise data and implement other functionalities. Circuit and working The circuit is built...

Smart presentation pointers are readily available in the market but are expensive. Here is a simple, easy-to-build, inexpensive and infrared (IR)-based smart slide pointer using Arduino Leonardo. Slide presentations using PowerPoint can be frustrating because you may need to click...
