In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.

In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino.

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

Did you know that a standard three-wire PC Fan can be used as a sensor?

A basic introduction to the low cost and accurate HC-SR04!

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.

This project will show how to set up a 16 x 2 LCD screen and display multiple sensor values.

In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.

This little project will show you how to use a soil moisture sensor.

Stream and analyze live data from your Arduino microcontroller into Excel with the Data Streamer add-in!

Need your project to gauge distance? Here's your module!

A system to maintain the pH level of a sample within a defined range.

This project will guide you to set up an alarm system using a motion detector.

My project helps visually challenged people to walk without crashing into walls and obstacles. This help them to live freely

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

I got my first Arduino recently, here I am gonna show you my first project which is Distance Measurement Using Ultrasonic sensors.

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

Using ultrasonic sensors to measure distance of obstacles, taking into account temperature and humidity that affect the speed of sound.

Code and explanation for getting directional and motion data from the raw sensor outputs.

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.

This project is an Arduino radar. It is a simulation of a radar.

Real-time pH and salinity monitoring with LED indicators.

If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.

In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.
