You'll use the same Adafruit library that you used in the previous chapters. If you have not installed this library, then install it and follow the instructions in Chapter 6, A Robot that Can Sail. Then create the following program:
When you run the program, you will see the output of the wind sensor in volts. You can put the wind sensor near a fan and you should see the value change, as shown in the following screenshot:
Note
Note that this will give you an indication of the strength of the wind, but the reading is not calibrated.
In this case, you won't need a calibrated reading but just a relative indication of strength; you'll then use it to gauge the direction of the wind. As noted earlier, you'll want to mount the wind sensor on a servo. This can give you a better indication of the direction of the wind with respect to the sailboat. To do this, connect the servo as noted in Chapter 6, A Robot that Can Sail. Connect the control wire connection...
