How to Make MP2.5 & Co2 Detect Wall Clock for Indoor using Arduino, MG811, GP2Y1014AU Sensor

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.

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

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!

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

We can measure body temperature without contact with this device.

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.

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

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