Analog reading from potentiometer connected to Arduino is displayed on Nextion & accordingly a slider is varied.
The command to Nextion is sent from Arduino as String followed by 3 times 0xFF.

How do you send the value of the slider from nextion to arduino? I tried ‘print slider.val’ but it returns ascii so I can't convert it to int. I also tried a covx but same problem.

Hi sure please I need a help
I create two number in my nextion
One to write a number who represent delay for my led
And other to recuperate this number and see the decremention started in the value of this number until zero
How I do this please

Hi, i follow exactly the video but it doesn´t work, i have the nextion NX3224K024_011 and arduino uno, , on arduino only blink LED TX, RX is always off, in my nextion when i slide the slider the value change, but with potentiometer never, in arduino (monitor serial) i can see that value changing when i move the potentiometer, can you help me ?

I am getting an error message as follows:
Error:Invalid command:n0.val = h0.val( Double click to jump to code)
Error:Compile failed! 1 Errors, 0 Warnings,
What could be the reason? I followed exactly according to your video.
