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

Create a burglar-tripwire with the ultrasonic sensor.

Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.

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

The ElectronicsLovers Tech Team built this module, which has one difference from a usual one: it’s digital.

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

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.

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.

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

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

Let us predict the changes around us with Arduino

Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

It is hard to measure the height of the children. So, we made Height Measure using distance sensor VL53L0X.

Arduino Nano and Visuino: Plot BME280 Temperature, Humidity and Pressure on Nextion Display Scope - Quick and Easy

Control the temperature of the rooms you are actually in

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.

Portable distance detection device using an Arduino and an ultrasonic sensor.

This is a low cost, modular smart board with wireless capabilities.

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

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

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

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

It can measure fine dust, humidity, temperature and CO2 concentration in the air and check it on the internet in real time.
