Hello, do yourself a favour and please read How to get the best out of this forum and modify your post accordingly (including code tags and necessary documentation of your ask).

I hope you don't mind that I took the liberty to change the sketch and see how far I got. That worked out pretty well if I may say so.

// Show progress bar with the full display width.
// 
// Possible update:
//   Only one custom character would be enough,
//   if it was created in the sketch every time.

This sketch in Wokwi (start the simulation and turn the potentiometer):

progressbar.ino - Wokwi Arduino and ESP32 Simulator

@serkansore You really have to put your sketch between code tags on this forum, otherwise it will be hard for us to help.

[serkansore]

Thank you works but reverse potatiometer volume up progressbar down

[serkansore]

Thank you no problem map code problem

[J-M-L]

You could have reversed the poles of the potentiometer

Posting a picture of a part of screen just to show the map command… don’t you think text would have been enough? (And clearer, and less energy wasted on the planet)
