The Petoi Light Sensor has two photo-sensitive devices (resistors) that respond to light intensity.
The "Analog Read" block returns a value between 0 (dark) to 1023 (bright).

Connect a light sensor to your Bittle using a Grove cable.
(Caution: When removing a Grove connector, be sure to press the latch on the connector before disconnecting the cable!)
Build the following program, and experiment with the light sensor.
Write a program that moves Bittle's head in response to a moving light source (like a flashlight.)
Hint: think about the difference between the left and right light sensors and which way the head should move
Write a program the moves Bittle (crawls, walks, ...) towards a light source.
