9.1.6 9.1.6 Test Result

After uploading the code, the servo rotates from 0° to 90° and delays for 1s, and then rotates to 180° and also delays
for 1s. At last, it back to 0° to repeat these actions.

9.1.7 9.1.7 Extension

We have learned how to set the servo to a certain angle without pause.
In this extension experiment, we program to control the servo to slowly rotate from 0° to 180° and then slowly back to
0° degree by degree.
