alligator robot coding
Brightness sensor and Opening/closing the alligator’s mouth
The brightness sensor should be used to close the the robot’s mouth, and the button sensor should
be used when to open the robot’s mouth. Do you rememner how the analog value changes when the
brightness value is covered? Keep in mind that the analog value increases when the brightness value is
covered and start coding.
If the brightness sensor
is uncovered, the
alligator should have
an open mouth.
If the brightness sensor
is covered, the alligator
should have a closed
mouth.
