Hi, the program uses a pseudorandom number generator to generate a number between 0 and 32767. This number is then divided by 128 to limit it between 1 and 255. The resultant number is sent to the PORTB of the microcontroller. This process is repeated every second.

Here is the code:

In the next lesson let’s make a programmed for internal weak pull-ups :)

And that’s it!

Thanks a lot! See you in the next episode.

Bye!
