√ Follow instructions with checkmarks on page 124.

counter VAR Word

STEP value controls the rate at which counter increases

Counter increments with FOR…NEXT loop.

As counter changes, so does the pulse width. As the pulse width changes, the servo’s position updates. Position changing over time gives an apparent velocity.

FOR counter = 1000 TO 500 STEP 10 PULSOUT 14, counter PAUSE 20 DEBUG DEC5 counter, CR, CRSRUPNEXT

Count down instead of up at a faster step rate.

Important – more info: √ Replace your pushbutton

circuits with this dial circuit. √ Remember to Leave the P14 LED and servo circuits connected.

√ Run ReadPotWithRcTime.bs2.√ Monitor time variable in Debug Terminal.NOTE: The pot must be firmly

seated in its breadboard sockets.√ Run ControlServoWithPot.bs2.√ Have fun controlling the servo with the pot.

Excerpt from page 148

√ Your course guide will explain how to adjust

the example program so that it works best with

the pulsout command and gives your servo a

range of motion that uses the potentiometer’s

entire range of motion.

√ Run ReadPotWithRcTime.bs2√ Twist the potentiometer’s input shaft,

and make notes of the time values displayed by the Debug Terminal.
