    Hello, I need an advice.
    I have a buzzer connected with arduino and i have another arduino connected with tha audio hacker shield and microphone
    I want to send some pulse with buzzer and receive pulses with the microphone and i want count the time between the impulses.

    I can do this?


    Yes, I think you could write some code to read the ADC and determine if the buzzer is sounding or not. If the values read from the ADC are significantly away from the silence baseline of 2048, then the buzzer is sounding. If you get a group of readings near 2048, then the sound has stopped. Give it a try.
