Nameplates are generally made of wood, acrylic sheet, or a metal and fixed on a wall or kept on desk. The author’s prototype of an acrylic nameplate that can display the...

Most multimeters make voltage measurements starting from one volt and some start from 200 millivolts. With such devices lower-value measurement becomes difficult, especially for DIY projects. Here is a circuit that...

Obtaining AC current readings from an AC wire helps us to know the amount of power that electrical appliances consume, promoting effective maintenance of the required load and supply. So today you...

This project presents an Arduino based speed monitoring system where the RPM (revolutions per minute) of a DC motor is continuously displayed on a smartphone using Bluetooth communication. The Arduino programming employs...

Linear actuators are widely used in robotics and mechatronics. But getting their accurate position is complicated. Linear Actuators are very costly (prices start from 10K) and can go up to several...

Managing the number of books present in a library or warehouse maintenance of several items is quite laborious and time-consuming. So for today’s project, we will be making a device that can...

This project is meant to control electrical appliances like fans and lights. You can configure two Yoda modules, one as receiver and the other as transmitter, to control relays that switch...
