The code is not available Pls help me

But why the light is blinking constantly after uploading the code.

With 1 LED instead of 5 LEDs, another example would be appreciated as the light intensity gradually increased as we approached, and decreased as we moved away. There are already too many of these examples.

Nice 👍

why does the code have 150 instead of HIGH for led output?

Is the code good?

What is the use of this project

Pls help me with the codes as it was not shown fully

This file is not supported very bad

CAN YOU GIVE CIRCUIT DIAGRAM
