The duty cycle of PWM (and therefore LED brightness) is calculated by scaling a 0 to 3.3 V input voltage, set by a potentiometer connected to an analog input pin. The blink interval is fixed and has ...

I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

Rotary encoder vs potentiometer A rotary encoder is a wonderful digital alternative to the old analog potentiometers. Rotary encoders are useful as rotation sensors (or selectors) and look similar to ...

This project was completed on a STM32 microcontroller and used a 3-pin RGB LED and a rotary encoder. The rotary encoder was used to select the channels of the RGB LED and change their intensities to ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: "I looked at all the available rotary encoder sketches ...

A measuring wheel is a construction measuring tool. The wheel rotates and, using basic rotational kinematics (s=rθ), you can determine the distance between two points. The video below shows a reduced ...

You can find the entire library online if you want to browse it without creating a project. Just to put this all in perspective, I joined the KY-040 encoder module with a KY-016 RGB LED.

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

The aptly named I2C Encoder V2 takes the form of a tiny smart board specifically designed for connecting multiple rotary encoders and is priced at just €6 or £5 and is now available to back via ...
