How to make a LED Spirit Level using Arduino and MPU6050 | LED Spirit Level

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.

Pulse induction metal detector, built on the Arduino Nano.

This device measures fine dust and NO2 concentration in the air while on the move and adds GPS coordinates to each measurement location.

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

Smarter Home Energy Use with Open Source and Cheap Sensors.

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

A super smart buoy with lots of sensors that sends data over radio to a base station where it is displayed on a real-time dashboard!

With only an arduino board, two servos, and an hc-sr04, and some python, you can create a room scanner that is capable of showing depth!

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

Create a burglar-tripwire with the ultrasonic sensor.

The lightmeter based on Arduino as a main controller and BH1750 as a metering cell. Information is displayed on SSD1306 OLED display.

This is a very precise scale for any weight up to 1.5 kg!

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

Follow this project to make an infrared thermometer by yourself!

Connect GPS and MicroSD Card to Arduino and log the GPS information - Quick and Easy

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

A low cost air quality monitoring device created with an aim to detect pollution hotspots caused due to traffic jams or factory emissions.

An Arduino based device to monitor the levels of combustible gases, carbon monoxide, relative humidity and temperature in the kitchen.
