PanTilt

How to use PanTilt library:

1. Import the library

from libCH.pantilt import PanTilt

2. Create PanTilt object, first parameter is the pin number of PAN servo, the second is Tilt pin number

motorPT = PanTilt(12,11)

3. Start to send PWM to PAN/Tilt servos(you will hear that the motor is turning)

motorPT.start()

4. Move right (or left) for X length ( 1 is about 18 degrees, if you want to turn right for 90 degrees,

the value for the parameter is 90, if you want to turn left for 90 degrees, the value is -90)

motorPT.movePAN(X)

5. Turn up or down for Y length ( 1 is about 18 degrees, if you want to move up for 10 degrees,

the value for the parameter is 0.56, if you want to turn down for 90 degrees, the value is -90)

motorPT.moveTILT(Y)

6. Turn right(or left) to xDegree position( xDegree's range is 2.512.5, corresponding to 0180 degree,

so, if the value for the parameter is 7.5, the servoo will turn to center position(90 degree))

motorPT.movePAN(xDegree)

7. Turn up(or down) to the yDegree position( yDegree's range is 2.512.5, corresponding to 0180 degree,

so, if the value for the parameter is 7.5, the servoo will turn to center position(90 degree))

motorPT.moveTILT(xDegree)

8. Stop sending PWM to Pan/Tilt (The servos of PAN/TILT will be stopped)

motorPT.stop()
