Hi people.
Can you help me with building a circuit with an LED that turns ON when you whistle, and OFF when you whistle again. It's a school project. It's should have the high pass and low pass filters.
I am supposed to measure the frequency on the microphone and an amplitude by whistling, then choose choose the capacitor values for the filters and calculate the gain and the resistor values.
For now I have measured the the frequency to be 2,016 kHz and amplitude to be 208 mV.
I now have no idea how to continue. Please help.
