An fun and simple project that uses TinyML to detect and respond to dog barks.

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

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.

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.

We can measure body temperature without contact with this device.

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

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.

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

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

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

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

This is a smart plant pot that can sense the plant's condition and shows an emotional expression (animation) for that condition.

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

Smarter Home Energy Use with Open Source and Cheap Sensors.

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!

This circuit measure the water level of a tank and wirelessly send it to a receiver where it is displayed using a LCD display and LEDs.

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

Create a burglar-tripwire with the ultrasonic sensor.

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

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!

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!
