I plan to use the Grove-Sound Sensor (http://www.seeedstudio.com/wiki/index.php?title=Twig_-_Sound_Sensor) for a project that can only supply an input voltage of 3.3V. However, the component itself is rated for a minimum input voltage of 4V.
My questions are the following:
Is it possible to modify the circuit (http://www.seeedstudio.com/wiki/images/b/be/Sound_sensor_sch.PNG to work with a supply voltage of 3.3V instead of 4V?
How is it possible (or impossible in case… )?
I really appreciate your detailed answer and would like to thank you all personally for the great help provided. Thank you.
Have a nice day,
