How does an Ultra Sonic Sound Sensor work?

• It converts digital signals into audible sounds
• It transmits Infared Light and calculates distance with a reciever
• It sends out sound waves with a transmitter and calculates distance when the sound returns to the reciever
• It detects changes in sound in the environment to count the number of objects in a given area

Which of the following is NOT a practical application of an Ultrasonic Sounds?

• Parking and anti-collision technology
• Distance calculation
• Temperature and humidity sensing
• Scanning internal organs or babies in the womb

What is the purpose of the command: GPIO.output(11,True) time.sleep(5) GPIO.output(11,False)

• It tells the computer to setup the GPIO Board and the 11th GPIO pin
• It sets up the 11th pin to be a ground
• It tells the computer it will need to use time and the GPIO pins
• It sends current through the 11th pin for 5 seconds and then turns off
