MATERIALS
- Flashlights, or cell phones as flashlights, to create a high light level
INTERMEDIATE: Add Sensors
Required lessons: Sensor Overview, Conditional Statements
When the lights are low, the CricketBot uses its buzzer to chirp like a real cricket. Full daylight makes it stop chirping.
For this project, the Finch should do the following:
- If the light level is high, the beak and tail should be green. The Finch should not chirp at all.
- If the light level is low, the beak and tail should be red. The Finch should chirp high and fast.
- You can use either left or right light sensor to determine if the light is low.
ADVANCED: Going Further
Required lessons: Control Structures & Line Tracking
When the lights are low, the CricketBot uses its buzzer to chirp like a real cricket. The darker it is, the faster it chirps. Full daylight makes it stop chirping.
For this project, the Finch should do the following:
- If the light level is high, the beak and tail should be green. The Finch should not chirp at all.
- If the light level is between high and low, the beak and tail should be blue. The Finch should chirp low and slow.
- If the light level is low, the beak and tail should be red. The Finch should chirp high and fast.
