Chapter 8, Programming Line-Following Sensors Using Python

• What can happen if the test track is too shiny or not dark enough?
  • The robot will fail to detect the track and may drive straight over it or jitter as it partially detects it.
• What are the other names for GND or G pin?
  • Ground, "-", negative, and "-ve"
• Why would strong sunlight interfere with this sensor?
  • Sunlight can flood the sensor with IR light, drowning out the sensors' own beam.
• In event-driven programming, such as we've used in this chapter, what do you call the section of code that will be called when an event is triggered?
  • Code triggered by an event is known as a handler.
