i have found this schematic and it looks simple to build... how will this work and how can i make my motor change directions automatically?

You need diodes on every transistor if you want to use this, to prevent your transistors from blowing due to back EMF...
Also, its a rather strange setup, i'm not sure it will work this way...
what do you want to accomplish? does it just have to reverse every X seconds by itself or ... ?
