SIE 370 Lab 4 Post-Lab Report &
SIE 370 Lab 5 Pre-Lab Report
Group Number: 16
1. Lab 4 Post-Lab Report
1.1 Lab 4 Overview and conclusion ( For the groups with 3 students, every group
member need to write a paragraph of overview and conclusion, put your
name after each paragraph. Groups with 2 students just need one for the
group. )
Overview – In Lab 4, we learned how to wire our Arduinos to a breadboard while
also adding code to them that would light up an LED or play a tune on a buzzer.
Conclusion – The main lesson we learned from this lab was that Arduinos are not
terribly difficult to program, however proper syntax is vital to ensuring that the
Arduino works how it should.
1.2 Lab 4 Post-Lab Questions
(None)
2. Lab 5 Pre-Lab Report
2.1 Lab 5 Overview and preparation ( For the groups with 3 students, every group
member need to write a paragraph of overview and preparation, put your
name after each paragraph. Groups with 2 students just need one for the
group. )
In the last lab, we had trouble with writing some of the code for the arduino to get
the song to play through the buzzer. After taking the midterm and learning more
about how to code in Arduino, we are more prepared to write the code for this lab.

We are also more familiar with arduino syntax and how to write certain constructs
in arduino.
2.2 Lab 5 Pre-lab Problems
Pre-Lab problem 1 : Details about the HC-SR04 ultrasonic sensor can be found
in the following link:
Read the document and answer the following questions:
What kind of signals should be sent to the trig pin that will let the sensor send out
a burst of ultrasonic sound?
