Light Chaser: An Automated Robot that Follows the Light

Harsh Sehgal 0 Comments

Hey there! In this tutorial, we're going to build a cool light-chasing robot that moves towards areas of bright light. To do this, we will be using photo resistors (also called photocells), which are light-dependent resistors that respond to the amount of light detected. This project uses an Arduino, an LDR module, and an...

Wireless Communication: Interfacing 433MHz Transmitter and Receiver Modules with Arduino UNO

Harsh Sehgal 0 Comments

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...

DIY Temperature and Humidity Monitoring System with Arduino and DHT22 Sensor

Harsh Sehgal 0 Comments

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...

How to build Robotic Arm using Arduino?

Harsh Sehgal 0 Comments

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...

How to make Arduino based Tachometer (RPM Meter) using IR sensor

Harsh Sehgal 0 Comments

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...
