Question 1.
What is the function of the Trigger pin in the HC-SR04?
Show hintHide hint
Think about which pin triggers the measurement process.
Question 2.
What does the Echo pin do?
Show hintHide hint
It's responsible for listening to the sound wave return.
3Question 3.
What does the Trigger pin do on the HC-SR04?
- Sends a pulse to measure
- Receives an echo
- Calculates distance
Show hintHide hint
Consider which pin starts the measurement process.
4Question 4.
True or False: The Speed of Sound is constant in all conditions.
- True
- False
Show hintHide hint
Think about what affects sound traveling through air.
Question 5.
You have an echo time of 25 ms. Calculate the distance the object is from the sensor and discuss how different conditions could affect this measurement.
Show hintHide hint
Make sure to convert milliseconds to seconds.
Question 6.
