Hi,
I'm currently really stuck in my project. I need to automatically get sound data from multiple destinations, fortunately not all at the same time. So I wanted to use a Pi Zero to activate a BS170 Mosfet for each mic, and testing to manually unplug pins (instead of the mosfet) from the mic on the breakout board successfully deactivated the unused mics. However, with the mosfet it didn't work anymore, at least for multiple mics without getting really bad noise. Now, I tried using a 74HC4051 for mic switching instead, but that doesn't work either.
Does anybody have an idea what could cause the issue or how to solve it?
Thanks in advance simultaneous
