Hey John pretty well laid out thank you. The code was pretty comprehensive as well for myself trying to learn and modify code to fit what I need.
Keep up the good work !

[@joshgapp1677]

Love it John. Nice mix of humor along with very thorough and easy to follow instruction.

[@robdavidowitz6428]

Crystal clear tutorial
Your explanations are SO clear and usefull.
Thanks👌

[@eddiejones8709]

Thanks for the video. Being a beginner at this your video really helps me better understand the sketch terms and building.

Has anyone attempted with an Arduino mega, even adapting the code doesn't seem to work

[@julioalbertodanoviz3854]

Excellent teaching method. Thanks.

[@chbonnici]

Very good ,clear, and sensible explanation. Well done and thank you. This is learning at its best.

Excellent explanation thanks I want make LCD menu for operate stepper motor with given speed and steps. thanks for your help.

Hi, I had an issue with the encoder not incrementing and was wondering if you had any ideas for me on that issue. The push button works fine but when I turn the knob nothing happens.

hanks lot Sir.. You helping us..

Hi John
I m new to Aurdino, saw ur vdo its very informative. want to have some more information on ur above vdo. Can we do preset counter using the above material. That is we set some count on LCD and when we rotate the encoder in reverse direction and as soon the counts reaches to "0" (zero) we can generate a flag which will operate a relay.
Can u help me in this above project with its sketch and bill of material.

[@Hossein_Ash]

Great Job. Thank you.

[@alexptvz1076]

man its very clean code and and very structured video. I repeat the same steps, but sometimes when I turn encoder value on LCD not been changed, it's like freezing for little time or some like this. Maybe you have an idea why it happens?

[@echosoundlight]

Thank for your video, can Rotary Encoder be connect to M5stack core 2 or Mstick C

[@sumeshak3477]

Hi can you please explain how to modify this program for OLED display?

[@luisfernandoalvarez5500]

Thanks a lot

John,
I have copied and pasted this sketch
Changed I2C adress to 0*27 and set the display 2 2*16
On compiling, I get the following error:

Can you please assist.

[@brraam007]

for me the lcd.begin(); does not work, but if i use lcd.init(); it does do you know why?
very nice video btw.

[@sarojpradhan4267]

HI John
I built this project and worked fine.
Now i want to realise menu system with the help from your code,
where rotaryleft and rotaryright function will navigate up and down through menu items and encoder click event will select the menuitem.
i tried one menu system using simple menu library.my problem is every function called in rotaryclick subroutine works perfectly but if i call same functions in rotaryleft and rotaryright subroutine it doesnot work. any idea?

[@alaskanbullworm1632]

Have you solved this?

[@Drxxx]

good tutorial!

[@christiankarlfrey766]
