## Step 1: calibrate servo
## Step 1: Calibrate servo
In order for the Milky Monster to move, the @boardname@ needs to command the servo to go between ``0`` and ``180`` degrees at a certain pace. In the code below:
- the user pressed button ``A`` to switch the servo to 180 degrees (to close the mouth of Milky Monster).
- the user pressed button ``B`` to switch the servo to 0 degrees (to open the mouth of Milky Monster).
- Press button ``A`` to switch the servo to 180 degrees (to close the mouth of Milky Monster).
- Press button ``B`` to switch the servo to 0 degrees (to open the mouth of Milky Monster).
