Copy colours from outside environment.

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

As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.

Create a burglar-tripwire with the ultrasonic sensor.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

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

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

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

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

FSM that allows to identify the direction of the object.

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.

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

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!

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

This project checks measurements automatically using lasers.

In this project, you can build and display a sonar system by using graphical programming software Kittenblock, developed based on Scratch3.0
