How to make a sensitive homemade lightning detector based on cheap AM receiver IC TA7642 and Arduino Nano.

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

An interesting way to increase sensitivity and reduce the noise of the ADXL335 analog accelerometer.

This is a thermometer intended for measuring the temperature in the room where we are staying, also known as room comfort thermometer.

It can detect metal coin at 15cm +, and bigger metal objects at 50cm and more. Also capable of discriminating between ferrous and nonferrous

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

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.

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

An air monitor that can measure CO, CO2, H2, CH4, NH3, Alcohol, Bangene, Acetone, Hexane, Toluene, Smoke and Flammable gas concentration.

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

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

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

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

He project is based on LDR sensor, I made the rotatable Solar system which has the home position during night time but when the light is ava

Portable range/distance detection device using an Arduino, ultrasonic sensor, and buzzer.

Build a weather station with Arduino & ASP.NET Core.

Variometer is instrument that indicates the changes in the altitude variations.

An object detection method using MobileNetV2 in Edge Impulse on Nvidia Jetson Nano to detect the pedestrian in blind spot region.

Super simple Weather station containing only two components.

An electronic spirit level using 'Motion Gestures' to get things horizontal OR to the slope of your choice!

Pressure tendency can forecast short-term changes in the weather. This is a very sophisticated device designed for sailors, yachtsmen, etc.

On this project I will show you how to measure the speed of movement of an object using HC-SR04 ultrasonic sensor.

In this case, it is interesting that are used two sensors to scan the entire 360-degree space.
