I have a question : The code explained by you is so simple and clear... well explained. Serial communication between Nextion and Arduino Uno is without using any library functions . what is your suggestion , is it preferable to use Nextion.h library? can you make a video with buttons and two sensor without library and with nextion library ?
thanx for video ,. its quite informative. I have a doubt... Serial.print("n0.val"); I am bit confused about this line... Does the value of "distance" will be assigned to variable "no.val" and does the next 3 , 0xFF, 0xFF, 0xFF will also be written in variable no.val ?? if we are another numeric object "n1"....same way we can assign value to "n1.val" ? I mean then statement Serial.print("n0.val") or Serial.print("n1.val") tell the nextion that next values will be assign to n0.val and n1.val ?
suppose int SerialValue; SerialValue= Serial.available(); What will be the value of "SerialValue" ? 1 ? or number of bytes available in buffer ? Second how we can use while loop to read all bytes in one go ?

Dear Sir
Thanks for useful video
Can you please share how can i get n0 value from nextion to arduino
I have just uploaded another video on Nextion you can that it will help u
thanx for video ,. its quite informative.
I have a doubt...

no.val is variable to which we give value and last OXFF is work as terminating command
realy sir this video is too informative
suppose int SerialValue;
SerialValue= Serial.available();
What will be the value of "SerialValue" ?
1 ? or number of bytes available in buffer ?
Second
how we can use while loop to read all bytes in one go ?
Awsm sir
Why is the title in English if the video is not?
