Place the object that you are about to protect on the PicoBoard/sensorboard's light sensor. Press the button on the PicoBoard/sensorboard then name the object that you are protecting. Make sure you have light shining on your PicoBoard/sensorboard in order for this to work. When someone steals your object, the alarm will go off telling you that someone stole something. The volume of the alarm noise can be adjusted with the slider.
