    I purchased an infrared emitter and detector (radio shack model # 276-0142), and trying to build a remote control button/switch that powers a 3V DC motor (range 1.5-3V). i don't know what other components i will need or how to setup the circuit.

    Too many questions, not enough info. Try to break it down, and give us a schmatic of as much as you can.

    You are going to need more than the IR LED and the photodetector pair to control a motor.....

    You will need a circuit to modulate a signal you are sending (on / off signal) for the transmitter, using a 38khz modulated IR transmitter/receiver would be a good start to google....

    You will also need a circuit to interface to the receiver that can handle the motor load... which should also incorporate a 555 timer IC for the on/off delays you want to implement....

    go here to Reynolds Electronics for more IR circuits and IC's >>>
