here is my circuit so far
IN THE PICTURE IVE GOT IT WRONG IT IS NOT LM351 ITS MENT TO BE LF351
i need the 20mV of the microphone to be 1.25v for the lm3916 using the lf351
so far if i connect pin 5 from the lm3916 to the microphone + pin all the lights light up but if i change the 1K ohm resistor to 20k ohm only 3 lights are on constantly and the other lights light up as you make noise but the noise has to be very close to the microphone and loud
can someone help me?
