How a Light Sensor Works
Let’s take a look at your Light Sensor’s values. Use a USB cable to connect your Studuino to your PC. Now
choose
Test ON
from the
Run
menu. Start Test Mode and you’ll see the Sensor Board displaying

The Light Sensor has a range of 0-100, with 0 being complete darkness and 100 being bright light. Now try
covering the Light Sensor with your hand while you look at the Sensor Board to see how the values change.
Once you’re finished, choose
Test OFF
from the
Run
menu to close Test Mode.
