Converting sounds into motion without a microcontroller Answered
I want to build a circuit which converts 3 specific frequencies into a voltage, then to be used by 3 different servos, I don't need to use a microcontroller!! what should I use other than microphone, op amp, 555 timer, servo and comparator for this circuit?
Which one is better LM567 OR LM2907 to convert the frequencies?
Thank you in advance!! Waiting for your reply ASAP :)
