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.

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

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

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.

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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.

The Arduino 9 Axes Motion Shield allows your Arduino to measure movement: orientation, acceleration and magnetic field.

Real-time pH and salinity monitoring with LED indicators.
