In this tutorial, we are going to make a circuit called a Contactless AC Detection circuit which will detect the presence of AC voltage when the antenna of the circuit is brought closer to the wire which is having a  supply. If the wire carries a current, it will sound like a buzzer with...

In this tutorial, we are going to learn how to use ultrasonic sensor HC-SR04 interfacing with Arduino and measure the distance which will be notified by 7 LEDs. As we move closer to the sensor the  LED will glow consecutively and vice-versa.   HC-SR04 Ultrasonic Sensor Pinout The sensor has 4 pins. 5volts is...

In this Arduino tutorial, we are going to learn how to use a motion sensor to sound a piezoelectric buzzer. The motion sensor used here is a PIR sensor which stands for Passive Infrared Sensor. This is great for an intrusion detection circuit or burglar alarm circuit. Whenever the motion sensor senses movement the piezoelectric buzzer will...

One of the most common ways of coding ESP8266, working with it and probably the simplest is by using ArduinoIDE. It might also be known that ESP8266 does not need any changes to be made on hardware level for us to code it with ArduinoIDE. This means, that ESP8266 comes with inbuilt Firmware that...

This is a simple project with one sensor used to detect the Gas Leak and one motor used to indicate the control. The microcontroller used is of course the simplest, Arduino Uno. In this project we’ll see how to use MQ2 sensor and how to control SG90 Servo motor and also use a buzzer...

In this project, let’s see how to make a simple bidirectional people counter using IR Sensors and Arduino Uno. This project will help learner to understand the working and application of IR sensor. The IR sensor is simple and powerful with wide variety of applications. This project will also help the user to understand logic...

In this DIY electronics section, let’s make an electronics dice using Seven Segment Display (SSD) and Arduino Uno. This is a simple and fun to build project, and the good thing about this project is that it can be practically used to play games! So let’s get started with this fun project!   Working of the...
