What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

The tutorial will focus on getting you up and running quickly, so that you will understand the basic procedures for working with your ESP32 (specifically the Adafruit ESP32 Feather v2) and the Arduino ...

The purpose of this sketch is to demonstrate a form of analog input using the potentiometer Grove. We will use this to set the delay for our blinking LEDs from project one. Connect the LED module to ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...
