Recitation 3: Sensors and our Terrible Security System

Introduction:

For recitation three, we were told to incorporate sensors into our projects. What were our projects? For the first time, we were allowed to build whatever we possibly could. For my project I wanted to make something with some sort of practical value, so my partner and I chose the vibration sensor. We wanted the vibration sensor to trigger a red light in addition to a speaker. In a sense it was a small security system. I really just hoped to learn how to apply my knowledge into a practical device and was really excited to try and do so. 

Security System:

When building the circuit, the hardest thing was decided what we actually wanted to build. Once deciding on a security system, we went ahead and got the necessary parts. By the grace of God, we actually managed to build this on our first try with no error. 

Here, you can see that we hooked up our sensor. We tested it with Analog Serial Read to make sure everything was in order.

After doing so, we added the LED to the security system. At first we wanted to stop here, but we knew we could do more.

Here you can see that we added a speaker. Furthermore, you can see my fist hitting the table and triggering the light. Though not possible to see through a picture, the speaker is functioning too.

This is the code for our security system: 

Reflection: Overall, it was a really fun process making this device. It was cool to see our knowledge manifest into an actual practical device. Being able to do such a thing only after three weeks gives me hope for what the future has in store. 

Question 1:

What did you intend to assemble in the recitation exercise? If your sensor/actuator combination were to be used for pragmatic purposes, who would use it, why would they use it, and how could it be used?

We intended to construct a security system through the use of a vibration sensor, an LED, and a speaker. We intended the vibration sensor to be under the floor and when someone were to step over it, it would notify someone through the flashing of a red light as well as an ugly sound. I think such a device has practical use. It is nowhere near as effective as an actual camera but it is a start. Anyone trying to defend themselves would surely appreciate it.

Question 2:

Code is often compared to following a recipe or tutorial.  Why do you think that is?

Let me preface this answer by saying I am an abysmal cook, so recipes are not my forte. I understand how coding can be related to one though. Similar to coding, recipes must be followed in the order they are presented to you. When coding, every line of code must be in the appropriate order or whatever you want to occur simply will not. No one puts their incomplete cake mix in the oven and cracks raw eggs onto whatever comes out. 

Question 3:
