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.

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.

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

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

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.

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

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

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

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

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

Build a simple incident light meter for old meterless film cameras

This project checks measurements automatically using lasers.

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

Monitoring temperature and humidity without using a WiFi connection. Suitable for a chicken coop.

An Arduino-based digital scale with HX711 and VFD display.

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