Speed

+ How To Add This Control To Your Project (Click to Expand)
  1. Load the most recent release of ARC.
  2. Press the Project tab from the top menu bar in ARC.
  3. Press Add Control from the button ribbon bar in ARC.
  4. Choose the Servo category tab.
  5. Press the Speed icon to add the control to your project.
This skill allows you to adjust the speed of a servo or PWM between two positions. It can be used for quickly identifying and experimenting with servo speeds for your application. This skill does not save the last setting or restore settings when the project is loaded.

*Note: Before this skill can be used, the servo position must be initialized. To do this, you can simply set the position with a script command or a servo skill. If you wish to have your robot initialize a servo speed when connected, use the Connection skill and the ServoSpeed() command in an initialization script.

Main Window



1. Servo Speed Slider
Press and hold the left mouse button down in this area to adjust the slider value. The range is 0-20. The lower the value the higher the speed.

2. Servo Speed Display
The speed value will be displayed here.

Settings



1. Title Field
This field contains the title of the skill. You can change it if you'd like. *Note: Changing the title will also change the title in the controlCommand() associated with this skill.

2. Board Index Drop-down
Select the EZB index number that your servo is connected to.

3. Port Selection Drop-down
Select the port number that your servo is connected to.

How to use Servo Speed


1) Add the Servo Speed skill to your ARC project (Project -> Add Skill -> Servo -> Servo Speed).

2) Add a Servo skill to your ARC project (Project -> Add Skill -> Servo).

3) In the Servo Speed skill settings select the port that you would like to adjust the speed of.

4) Adjust the servo speed in the main window of the Servo Speed skill.

5) Move servo with the servo skill and watch as it matches the speed set by the Servo Speed skill.

Speed : Delay for ezb v4
===========
10 = 100 ms 
9   = alternating between 80, 100 ms
8   = 80 ms 
7   = alternating between 60, 80 ms
6   = 60 ms
5   = alternating between 40, 60 ms
4   = 40 ms
3   = alternating between 20, 40 ms
2   = 20 ms
1   = 20 ms, but the angle step is 2 or -2

The delay of speed is discussed here
