Push button controller

Kojanow

I am making a project with two servo's and two pushbuttons, one to acuate each servo.· The servo's are moving fine but I can't get teh push buttons to control them.
This what I have· HELP!

Hi Kojanow,

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.

You'd do better to sort everything into methods. A good start would be to have a _Main method, _Rotate_Servo_1, and _Rotate_Servo_2. That way you can keep everything clear and easy to debug.

I agree with SRLM that organization would be helpful here. In PBASIC you would be using subroutines. What's a Microcontroller? introduces subroutines on page 206.

Thanks all, I will be working on this tonight.
