You now know that you can talk to your servomotor controller, and move your servos. In this section, you'll create a Python program that will let you talk to your servos to move them to specific angles.

Let's start with a simple program that will make your legged mobile robot's servos go to 90 degrees (the middle of the 0 to 180 degrees you can set). This particular controller uses bytes of information, so the code will translate the input of the channel and angle to numbers that the controller can understand. For more details, see http://www.pololu.com/docs/0J40. Here is the code to move all the connected servos to the 90 degree point:

Here is an explanation of the code:
