Good Morning EZ-Scripters !
Attached is my crude attempt to use and display the PWM Value.
:Start
#
PWM(D19,50)
#
:Loop
#
$x=GetServo(D19)
#
#WaitForChange($x)
#
Print($x)
#
Goto(Loop)
#
PWM(D19,50) initializes to 50%, and the Slide Bar changes its value, but my Print Value does not change ?
Thank You All & Best Wishes,

PWM = Pulse Width Modulation
SERVO = A device used to provide control of a desired operation through the use of feedback
Every control has ? next to the X (close). If you press the ?, you will be directed to a tutorial page for that control. I suggest viewing the PWM control tutorial and watching the video. It explains a little of what PWM is. PWM will not work with the Roomba. The roomba speed is controlled by SetSpeed() and GetSpeed().
The EZ-Script manual is next to the editor.
Thank You for both your Tutoring and your Patience with the aged.
Your PWM Video is GREAT !
Cleaver how you used a Single Ribbon Cable from multiple EZ-B Ports to the H-Bridge.
It's now on to GetSpeed() & SetSpeed() !
SetSpeed( speed )
Sets the global Movement Speed value
Example: SetSpeed(50)
GetSpeed( )
Returns the global Movement Speed value
Example: GetSpeed()
Thanks Again,

It means a lot to me when I see someone find the solution with a little guidance - rather than doing all the work. Kudos!
