How do I connect a switch to act as the reset button on my board of education

mimic

I have a program that turns a servo counterclockwise so many pulses and then clockwise so many pulses.
I want to have a switch that will start the program every time I hit the switch or button.
Here is the code for my servo· I am sure that I will have to add to it to make the button work.
Any advice

counter VAR Word
DEBUG "Counterclockwise 10 o'clock", CR
FOR counter = 1 TO 150
PULSOUT 14, 1000
PAUSE 20
NEXT
DEBUG "Clockwise 2 o'clock", CR
FOR counter = 1 TO 150
PULSOUT 14, 500
PAUSE 20
NEXT
DEBUG "Center 12 o'clock", CR
FOR counter = 1 TO 150
PULSOUT 14, 750
PAUSE 20
NEXT
DEBUG "All done."
END

On the BOE press the little button just above the power switch (marked reset)

Wire a button as explained in the WAM text or on pages 141-143 of the PBASIC Reference Manual.· I can't test this program, as I'm far away from my hardware, but it should work.· When running, it will sit there and do nothing until you press the button.· Once the button is pressed, the servo routine will run, then it'll wait for another button press.· Please note that pressing the button while the servos are moving will do nothing!· It will only read the button again once the servo move routine is completed.

There are other, maybe simpler ways to do this too, such as using INPUT, with a DO WHILE or DO UNTIL type of loop.· It's up to you, this is just a suggestion.

You could have a normally closed switch between your power supply and boe.
