Use a ratiometric linear Hall effect sensor to build simple magnetic field strength meter.

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.

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!

Create a burglar-tripwire with the ultrasonic sensor.

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

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

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

Build an Arduino heart rate monitor with a MAX30102 sensor and a 16x2 LCD.

Remote temperature monitor using a Bluetooth module and an NTC thermistor. An Android app made with App Inventor is used to read data.

Senses for smoke in the air near a 3D printer and will sound an alarm and turn off power to the printer if smoke is detected.

An Arduino based device to read multiple DS18B20 sensors and send the values through a RS232 connection to a domotica system.

I am back again with another Arduino based home automation project.

Copy colours from outside environment.

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

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

Build a simple incident light meter for old meterless film cameras

This project checks measurements automatically using lasers.

Evaluate the amount of the energy generated by a solar panel at a given direction through light intensity levels.

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

An automated humidor using an Arduino — with or without building your own humidor.

FSM that allows to identify the direction of the object.

Despike/smooth data from a DHT22 with a median filter and display on a 0.96 inch OLED with the date and time from a DS3231 real-time clock!
