3. Connect the yellow wire from the servo to digital pin 9. It should look
something like
Figure 3-19
or
Figure 3-20
.
4. In the Arduino IDE, enter the code from
Example 3-4
into a new sketch.
5. With the Galileo powered on and connected to your computer via USB,
upload the sketch to the board.

Wiring up a hobby servo to Galileo
If you have everything wired up correctly, you should see the servo swing
back and forth (see
Example 3-4
)!
