Simple Millivolt Meter Using Arduino
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...
AC Current Monitor Using Arduino
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...
DC Motor RPM Display On Smartphone Using Arduino
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...
Position Controlled Linear Actuator with mm Level of Accuracy
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...
RFID-Based Automatic Management System
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...
Appliances Control With Yoda Module And Arduino
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...
Android Application For Multi-Sensor Data Monitoring
This Android-based project can monitor on-site (field) process data sensed by two temperature sensors and display the temperature (in degree centigrade) on a smartphone. The authors’ prototype of the project is...
Rail Track Temperature Monitoring System
All Indian Railway Permanent Way offices monitor rail tracks to record their maximum and minimum temperature of the day at hourly intervals. It is done to check the metal shrinkage during...
COVID-19 Ventilator and Health Monitoring Device
At this time of COVID-19 outbreak, the demand for ventilator and health monitoring devices has increased with each passing day. To overcome the shortage of these devices, we don’t have any...
Radar and ROS Powered Indoor Home Mapping and Positioning Robot
The indoor mapping and positioning feature of a Robot Operating System (ROS) controlled robot is essential in navigating through a hall, warehouse, room or in any other environment.
Since many find it...
