A 433MHz transmitter and receiver pair uses Amplitude Shift Keying (ASK) modulation to transmit and receive data wirelessly. The transmitter modulates a 433MHz carrier wave with the data signal using an ASK modulator, and transmits the modulated signal through an antenna. The receiver picks up the transmitted signal with an antenna, filters out unwanted...

In this article, we will learn about how we send temperature and humidity data from a DHT22 sensor and displays it on an LCD screen using an Arduino board. The LCD screen is initialized with its pins and dimensions, and the temperature is printed in Celsius or Fahrenheit depending on the value of a boolean...

A robotic arm is a type of mechanical arm, usually programmable, that is designed to move materials, parts, tools, or specialized devices through various types of programmed motions for the purpose of manufacturing, assembly, testing, inspection, and other tasks. Robotic arms are widely used in a variety of industries, including automotive, aerospace, electronics, food...

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...
