Comments
Are you starting with What's a Microcontroller, Chapter 4, Activity #4? It shows how to use two pushbuttons and one servo, one pushbutton makes it turn one way, the other pushbutton makes it turn the other way.
The important thing is to have your pushbutton state trigger an action. In the program above, your if-then statement for your pushbutton (if it is connected to P3) only causes P0 to turn on and off once. There is no relationship to your servos on P8 and P15.
