i had got it to work but i could not know what is the range of the beep time and frequency
they only mentioned the type (int) but they had not mention the range in the documentation
any help?
There is an updated library that fixes an issue with higher frequencies. The values limits depend on the actual sound. If the frequency is too high the sound will be annoying.
Note that it is recommended to reuse the same Beeper object and you need to call Beeper.Release when you are done with it.
