Arduino Sleep & Wake Up for Microseconds

Hi,

Is it possible to make Arduino sleep and wake up for about 50 microseconds?

Thanks.

Do you want it to wake up every so often or when triggered by some event ?

I want to make Arduino sleeps and wakes up frequently for every 50 microseconds.

Example:
50us wake up
50us sleep
50us wake up
50us sleep

I see nothing relevant there or must I register first?

If you just want to delay rather than sleep.

Sleep for 50us seems a really small time, what’s the reason or goal.

The reason is to save power by sleeping.

Why 50 µS? What is this project doing exactly?
