Hello, need urgent help. We are doing this project
But the coding does not work.
we are not using the ir sensor.

Did you read the comment to do the wiring?
Why does
your code
wander
around
the
page?
What can you see on the serial monitor?
Also 'coding does not work' is a really bad description of your 'fault'.
Posting your code was only part of what is required from you if we are to help. What does the code fail to do that you want it to do? What does the code do that you don't want it to do?
