Plant Monitoring Robot unable to upload code

I am not able to upload code for the plant monitoring robot.

An error is coming![:point_down:]


  1. You did not save the file. (Go to File> Save, provide a name and save the sketch)
  2. You did not select the port. (Go to Tools> Port, select the port connected with your PC)

All of this was already provided in the very beginning of training.

(timestamp 4:15)

Make sure not to skip any of the module. And let me know if you have any other queries.

First of all save this file and also select the port.
