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...

Real Time Heart Rate Monitoring System Using Arduino

Harsh Sehgal 0 Comments

This project is an Arduino-based heart pulse sensor that uses an OLED display to show the user's pulse rate. The program uses an analog heart rate sensor connected to pin A0 of the Arduino board. The code reads the sensor values and maps them to a range between 0 and 45 to create a...

Arduino Based Light Following Robot with LDR Sensor

Harsh Sehgal 0 Comments

In this tutorial, we are going to make a light-chasing robot that moves toward areas of bright light. We will be using photoresistors to determine the brightness of the light. For a better understanding, have a look at the line following robot, surveillance robot car, obstacle-avoiding robot that we previously created. A photoresistor, or photocell, is a light-dependent resistor...

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...

Line Follower Robot using Arduino and L298N Module
