Do you want to know how to use an Arduino with a real-time clock (RTC) module?  Well, you’re in the right place! In this article,

This article will teach you how to drive a 12V DC motor water pump using Arduino.  These DC motors are used in aquariums, indoor gardens,

In this article, you learn about using NPK sensors with Arduino. NPK (Nitrogen, Phosphorus, and Potassium) are plants’ three vital macronutrients.  You can use the

This article will teach you how to interface an Arduino with a light sensor built on LDR. LDR stands for ‘light-dependent resistor’. These light sensors

In this article, I will show you how to control a fan with an Arduino UNO board.  Fans are a common household item often used

In this article, we will build a tachometer. A tachometer measures the number of rotations of a wheel, fan, engine, etc.  We will use the

In this article, you will learn how to interface a thermocouple to the Arduino UNO.  There are several types of thermocouples with a wide range

Measuring carbon dioxide (CO2) in the air can be very useful in monitoring indoor air quality, as well as levels of pollution in the atmosphere.

The CCS811 VO Sensor is an ultra-low power gas sensor that integrates a metal oxide gas sensor that detects a wide range of Volatile Organic

A tilt switch is a device you can use to detect a tilt.  In this tutorial, we will learn about how a tilt switch works

Do you know that oxygen sensors are widely used to save thousands of lives? The sensors monitor air quality in hospitals, houses, mines, industries, and

The number of GPIOs on the Arduino can sometimes feel a bit limited.  For example, if you have a project where you want to control

There are many temperature sensor options to utilise when sensing the ambient temperature with Arduino.  You can use NTC/PTC, thermocouple or an RTD sensors. When
