@mani2474695 Can you please share the screenshot of the error? Also, is this the complete code that you have entered in the Arduino IDE?

Hi,

You have two files open in the Arduino IDE. One of them is the file named “Bolt_Robot_Car” and the other one is the file named “Bolt_Robot_Car.ino”.

I believe you have the same code written in both these files. You need to delete the full code from 1 of these files to allow the code to be compiled.
