In this tutorial, we are going to make Digital Tachometer using an IR Sensor with the help of Arduino for measuring the number of rotations of the rotating Motor in RPM. Here we have interfaced the IR sensor module with Arduino and the 0.96 Inch OLED display to display the RPM count. The IR...

Robotics is an interesting and rapidly growing sector in this era. As a branch of engineering, the applications of robotics are numerous.  It is Increasing with the advancement of technology at a decent pace. Previously we made Line Follower Robot and Surveillance Robot. Obstacle avoidance refers to the ability of a robot to detect obstacles...

The line follower robot is an automated vehicle that follows a visual black line or path on the surface. This visual line is a path on which the line follower robot moves. It uses a black line on a white surface, or you can also adjust it as a white line on a black...

Let’s take a look into a simple interfacing project this time. This is actuator interfacing with Arduino Uno and the actuator being servo motor, specifically SG90 servo motor. SG90 is a lightweight (just 9g) and tiny servo motor which has quite good output toque. We can use Arduino IDE to code this servo and...

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...

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...
