Import the servo and serial port libraries



In [70]:

    
import serial
import Servo
import time



In [3]:

    
from IPython.html.widgets import interact









    



:0: FutureWarning: IPython widgets are experimental and may change in the future.

Open the serial port



In [4]:

    
sp = serial.Serial("/dev/ttyUSB0", 19200)

Create a servo object



In [44]:

    
a = Servo.Servo(sp, dir = 'a')
b = Servo.Servo(sp, dir = 'b')
c = Servo.Servo(sp, dir = 'c')

Move the servo for testing. Change the pos value



In [38]:

    
a.pos = 60
b.pos = -60

Interactive widget for moving the servo



In [69]:

    
w1 = interact(a.set_pos, pos = (-90, 90))
w2 = interact(b.set_pos, pos = (-90, 90))
w3 = interact(c.set_pos, pos = (-90, 90))



In [68]:

    
for i in range(2):
    c.pos = -60
    time.sleep(1)
    c.pos = 20
    time.sleep(1)
