1. Programming a Servo
By Joshua Shaw

2. From the last Power Points
We have previously added a While Loop
We are now going to use it for programming the robot
We have also added two motor programs
An analog program
A digital program

3. Servo Programming
Now lets make a servo operate with the flip of the joystick on the Joystick Controller
Go back to Joystick in the Function Block
Click and drag the Joystick to Servo function to your While Loop and place it on the vertical line between the JoystickToMotor function box and the lower bracket box

4. Servo Programming cont’d
When you do this, another dialog box will appear
For our example program
Lets set the Channel to “2” and the Motor to “4”
This is done by click the down arrow besides each of the boxes
Click OK

5. Using the Joystick Controller – Channel 2
You will use the Channel 2 on the Joystick Controller
Move the right joystick up or down to control the servo
The servo will only move about 60º in either direction for a total of 120º

6. Servo Controlled by Buttons
We will now create a servo program that operates with buttons instead of the joystick
Go to the Function Block
Under the Joystick folder
Click and drag the Joystick Digital to Servo onto the vertical line between the bracket boxes in the While Loop

7. Servo Controlled by buttons cont’d
The program for the servo in this example will look similar to the default
The difference is that the Servo # will be “3” and not “2”
Change the number by clicking on the down arrow
Then click on the “3”

8. Completed Servo Controlled by Buttons Program
The final program for the servo will look like this
Finally click OK

9. Using the Joystick Controller – Channel 5
You will use the Channel 5 buttons on the Joystick Controller
Push the top left button to move the servo to the left
Push the bottom left button to move the servo to the right
When you let off of the button the servo will return to neutral
To change the direction of the servo, first release the button being pushed.
