Rotary Encoder: What is and How exactly Works and How to Interface

rotary encoder is a very useful component which sometimes is wrongly called digital volume or digital potentiometer.
This little component informs every CW or CCW rotations of its handle to our system by digital signals and often used for selecting something.
In this video, we will discuss about different types, take it apart and take a deep look at its mechanism and we will test it and find the best way to interface it with any MCU.
If you turn it's handle you will sense the steps on your fingers, like when you turn stepper motor’s shaft. This device should detect every movement and turning steps and direction of rotation and has a hidden push button as additional feature.
This module has five pins, two of them are for power the module up, one of them is for push button and two remaining are for rotation signals.
There is two resistors for pulling signal pins up and they are necessary for interfacing this device with MCUs.
I hope you enjoy watching this video. Please subscribe my channel for more XE videos.

Wonderful explanation! You have a gift for teaching.

[@XEMC]

Thank you! 😃

[@nsnowaz]

Your concept is like magic . Your very hard workers for making this type of delicious content

[@XEMC]

Wow, so glad you think so 🤗

[@hectormata449]

Electronic terms most offend sound like some complicated electrical system beyond the knowledge of non science types like me, but this video was very enlightening and understandable. Kudos teacher

[@XEMC]

Glad it was helpful 😊

Merci pour cette excellente présentation du principe de fonctionnement de l'encodeur rotatif! Maintenant que vous nous avez bien mis en appétit, vous êtes un peu obligé de poursuivre avec une belle application, visualisée à l'oscilloscope, etc. etc.... 😜

Can we connect Vcc at gnd ? If not why

Glad you enjoyed

what a explanation..

[@moulaali9]

Excellent

[@XEMC]

thank you dude 🌹

Cool. Very informative. Now, how to convert the rotary signals into vol up and vol down...

[@imlassuom]

Excellent explanation but I wonder the "Volt" word in what script was written?

[@XEMC]

thank you, it is better to use "Volts" instead of "Volt".

[@stefano.a]

@@XEMC I think that Imla Assuom refers to the way is the letter "V" is written. In a point in the video there is the word "5 5" meaning "5 V" in other part seems that the unit of measure "V" is written in superscript (as it was an exponent of the number)

Where can one get that power supply? :)

He made it in one of his video

@@newstar346 Thanks - that video came out after my question so I'm glad you pointed it out to me :)

The rotary encoder .must be connected to an up down digital counter.zThis waythe fake encodercan mimim areal potentiomter. Personally, I dont like them my car radio has them They suck! i love old style potentiometers.
