Phototransistor Circuit for Motor Control

[Microhoo]

Hello, I have been working on a little thing and I bought 2 Infrared Phototransistors(http://www.radioshack.com/product/index.jsp?productId=2049724"). What is wrong with my circuit? Thanks.

Your post makes no sense without showing us a schematic.

It sounds like you are trying to drive a motor directly with a phototransistor.

This is unlikely to work because the motor needs a lot of current to work and the phototransistor is unable to supply this.

There was a similar thread last year and you might like to have a read through it and a look at the drawings in it. There were several circuits that would possibly help you.

Your motor would be switched by the relay contacts at the right of the various circuits.
Be careful to include the protective diode where shown in the circuits.
