i am new to most of this so my confusion is basic. here is my problem.
I am using a 555 timer to create a squarewave frequency of between 20-80khz
BUT the output is 1vpp. i am using this to drive a motor and need to up the voltage and current. i know what i need to use i just can't for the life of me figure out how to set up the op-amp to get say 5v's or so.
after the opamp i plan to use a transistor in an emitter follower configuration to drive the motor
