Question

1. In programming the servo motor using the BASIC Stamp microcontroller what command really controls the position of the servo? What is the name of the argument in the command that, if changed, will cause the servo’s position to change?

Answer 1

Solution -

To control a servo from a BASIC Stamp microcontroller is to use the PULSOUT command. This command sends a pulse of any duration you specify to an I/O pin of your choosing. The syntax of this command is

 PULSOUT pin, duration

You specify the duration in units of two microseconds. A microsecond is one-millionth of a second. There are one thousand microseconds in a millisecond. Thus, to send a 1.5 ms pulse with the PULSOUT command, you must specify 750 as the duration, like this -

 PULSOUT 0,750

PIN is used for the input-output like at PIN 14 we have defined to hold the servo at 45 degrees so above expression will become -

PULSOUT 14,750

Ofcouce on the change of the PIN the position will change so the answer is yes .
