Let's say I have a switch between a small motor and its powersource,
I need that switch to be turned on whenever it recieves and audio tone and I need it to turn off whenever the tone stops, how could I accomplish this?

basically:
I need the switch to be on when it recieves the tone and to turn off when the tone stops

thanks

What are the voltage and current demands of the motor?

What frequency is the tone?

What is the voltage of the tone?

Read the data sheet for a NE567 ; should work well by driving a relay trough a transistor.
