Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

In this tutorial I am going to show you how to build a Wireless Weather Station with a big 3.2" Color TFT display using Arduino.

Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.

The detector can detect a small metal coin at a distance of 15 centimeters.

In This Tutorial, I will Show You How to Make an Arduino Based MPPT Charge Controller

We can measure body temperature without contact with this device.

Easy to build, but comparable with professional seismometers, homemade Arduino seismometer.

Let us predict the changes around us with Arduino

A cheap DIY air quality monitoring device.

Follow this project to make an infrared thermometer by yourself!

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Pulse induction Metal Detector. It can detect a metal coin at a distance of 15 cm and a larger metal object at a distance of 40 cm and more.

Very simple air quality monitor with nice processing graphical interface oh PC monitor.

DIY Arduino air quality monitor which can measure surrounding air quality also shows temperature and humidity in your room.

This project will demonstrate how to build a water level monitor using an Arduino Nano, a Solu SL067 water level sensor, and an indicator.

It is hard to measure the height of the children. So, we made Height Measure using distance sensor VL53L0X.
