Hello everybody,

I try to delay OUT_Buzzer for 30 sec with millis, but i am not able to use millis, can you help me please? :slight_smile:

Hello,

Your sketch will not compile, as posted. Post the last working version you have, and explain in more detail how you want to change it.

You can only use the millis() function if you include it in your code. At the moment it is absent which is why it doesn't work.

There is no reason why this function can not be included in your code.
