In this post I will show how to construct wireless office calling bell which can be used for calling 6 different personnel from head’s / boss’s desk or some other calling bell type fun project for your home. Using nRF24L01 2.4 GHz module We will be constructing a simple wireless calling bell using Arduino and nRF24L01 […]
Newly Updated Circuit Projects:
100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown
In this project we are going to make one very useful grid power protection circuit. This will be like a power guard system which we can use in homes or apartments to monitor the wattage of the load and also to cut off the load automatically if it starts taking too much wattage, more than […]
Smart Bathroom Exhaust Fan Controller Circuit with Sensors
So here we are now making one automatic smart exhaust fan controller system using Arduino UNO which will work for three bathrooms that are all connected to a single ventilation pipe and one common exhaust fan. This whole project is going to be based on PIR sensors for human detection, VOC sensors for odor detection […]
Cellphone Controlled Dog Feeder Circuit
A cellphone controlled dog feeder is feeding system for pets and animals which allows a remote controlled refilling of food in the container of the feeder by the owner, without physically attending the place. A GSM module and Arduino based dog feeder circuit is discussed in this post. The system can be used for operating […]
50 Best Arduino Projects for Final Year Engineering Students
In this post we sort out a list of most popular, 50 hand-picked and best engineering circuit Arduino projects specially created for all aspiring engineers for their final year project exhibition. The circuit projects include the latest and advanced microprocessor Arduino based designs with full program code. The list also includes projects using discrete parts […]
Automatic Ultrasonic Water Pump Motor Controller Circuit
This project explains how to build a fully automatic ultrasonic water level controller where the water pump motor starts automatically when the tank level goes below a preset LOW level and stops automatically when the tank becomes FULL. The whole system is wireless, reliable, and there are no corrosion problems because the ultrasonic sensor never […]
