Electronics Projects

In this project we will use an existing FM radio which went repair a long time ago, to convert it into a Smart Wireless FM Radio controlled using Phone, with the help of Arduino and Processing.

We can convert any manually operated electronic device into a Smart Device using the same procedure.  Every electronic device operates with the help of…

In the world of Internet of Things (IoT) when we have all the technologies to revolutionize our life, it's a great idea to develop a system which can be controlled and monitored from anywhere.  There are many types of good security systems and cameras out there for home security but they are much expensive so today we will build a low cost simple Raspberry Pi based…

This tutorial is the continuation of the previous tutorial Getting Started with ESP8266 (Part 1). So, to give a small recap, in our previous tutorial we introduced our self to the ESP module and learnt few basics about it. We also made a development board, using a FTDI Serial Adapter Module, which can be easily used to program the ESP module using both using AT commands and…

Ever wanted to build a Face Tracking Robotic Arm or Robot by simply using Arduino and not any other programming like OpenCV, visual basics C# etc? Then read along, in this project we are going to implement face detection by blending in the power of Arduino and Android. In this project, the mobile camera will move along with your face with the help of servos. The advantage of…

Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions, like ball valves which automatically stop water flow once the tank gets full, electronics enthusiasts prefer smart electronic solutions. This comprehensive water level indicator project tutorial will guide you to build a simple DIY water level indicator circuit that…

Fire alarms are a prime necessity in modern buildings and architecture, especially in banks, data centres, and gas stations. They detect fire in the ambience at a very early stage by sensing smoke or heat and raise an alarm, which warns people and gives them sufficient time to take preventive measures. It not only prevents big losses caused by deadly fire but sometimes…

In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. In Our previous Projects we have made some robots like line follower, DTMF controlled robot, gesture controlled robot, computer controlled…

Security is main concern for various buildings, houses and offices. There are a variety of security alarms available in market which uses various types of technology for intruder detection like infrared sensors, motion sensors, ultrasonic sensors, laser sensors, etc. Previously we have also built some security alarm circuits like this PIR sensor based motion detector and…

Small Loudspeaker is a fun project to do, you can connect it to your Cellphone or Laptop through a 3.5mm audio jack and can enjoy your own loudspeaker. You can also connect it to any device which has a 3.5 mm audio output, like TV, music player, video games etc. We have used LM386 IC to amplify sound, with a few external components.

We all know that one of the places where power wastage occurs most in homes and offices is at staircases. We usually turn on light at stairs and leave it in a hurry. In this project we are going to design a stair case lamp which works on battery and only turn on the lights only when someone is present at there. This circuit can be used to save power and it can be used as an…

Humidity and temperature are common parameters to measure environmental conditions. In this Arduino based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined temperature and himidity sensor DHT11 is used with Arduino uno to develop this Celsius scale thermometer and percentage scale humidity measurement project. In…

Line follower Robot is a machine which follows a line, it may be a black line or a white line. Basically two types of line follower robots are: one is black line follower which follows black line and second one is white line follower which follows white line. Line follower actually senses the line and run over it. In our previous projects, we have made a black line…
