Course Project Overview
TABLE OF CONTENTS
Course Project: Technology Implications In My Professional Life
Objectives
A variety of recurring topics, which are part of your educational journey and professional career will be discussed in this course. These topics; which are not limited to: (a) problem solving, (b) network communications, (c) communication and ethics, (d) computer information systems, (f) cyber security, (g) game design and web design, (h) electronics, and (i) professional organizations will be discussed over and over during your educational journey at DeVry University and professional career.
No Final Exam is required in the course. However, a Final Course Project Presentation is required, in Week 8, in which you will present a summary of your Raspberry Pi project.
Guidelines
Course Project
Having had the opportunity to set up and run your Raspberry Pi (RPI), you may start to develop your own RPI project. Please search the Internet for project ideas and come up with a favorite project. If you are dissatisfied with the Internet project choices, then the following 10 projects are available along with their required project scopes. Please select only one from the listing and plan to purchase required additional components for the project.
I. A jukebox that plays at least 3 of your mp3 files. Before beginning, ensure that you have headphones or speakers plugged in.
1. Notes: To test if your sound works, plug your speaker into the audio jack and install mpg123 with the command: sudo apt-get install mpg123
2. You can test your sound with an mp3 on your Raspberry Pi in this location: /usr/share/scratch/Media/Sounds/Effects/WaterDrop.mp3 after you install mpg123. Use the following command to copy this mp3 file to your own directory:
3. cp /usr/share/scratch/Media/Sounds/Effects/WaterDrop.mp3
4. Be sure to include the . at the end. Test to see if it works with this command:
5. mpg123 WaterDrop.mp3
6. Note: If you are using headphones, you may need to change the audio output to headphones with this command: amixer cset numid=3 1
7. Install LXMusic with the command: sudo apt-get install lxmusic
8. After it has finished installing, run lxmusic by typing lxmusic at the prompt. Add your mp3 files and play your music!
9. Optional: Set up a share so that you can access mp3 files from your Windows computer and connect using the Pi. Try this site: http://www.lifehacker.com.au/2015/06/how-to-build-a-raspberry-pi-jukebox-any-non-geek-can-use/ (Links to an external site.)Links to an external site.
II. Creating a basic pong game with pygame: This basic pong game will only move a ball back and forth when you press the right and left arrow keys. Once the ball touches the rectangles, it turns them purple. Optional: Make at least three modifications to the code. Some ideas are below:
1. You can modify the code to allow the ball to move up and down.
2. Add another key stroke to do something (turn the ball a different color, or change direction). Key codes are here: https://www.pygame.org/docs/ref/key.html (Links to an external site.)Links to an external site.
3. Change the ball’s color.
4. Change the color of the rectangles.
5. Add your name to the screen.
6. Move the rectangles.
7. Anything you can imagine!

IV. Understanding electronic circuits with the RPI:
1. For this project, you will need some extra components. Hook up the GPIO pins on your Raspberry Pi. Add a resistor, an LED light, and a ground wire. Please note: It is important to put your LED in the correct way (the shorter end should be in the same row as the resistor), and your ribbon cable needs to be plugged in correctly. Research the pins and determine where to put the resistor and light. For information, see this site: https://www.raspberrypi.org/documentation/usage/gpio-plus-and-raspi2/ (Links to an external site.)Links to an external site.

2. Write a Python program to make the light blink: http://www.rpiblog.com/2012/09/using-gpio-of-raspberry-pi-to-blink-led.html (Links to an external site.)Links to an external site.
3. The Python code to make the LED blink is below. To run it, be sure to save the file in your home directory (example name is ledblink.py), then run it with sudo python ledblink.py on the command line. Code follows for Pin 11 (which maps to Pin 17 on the board):
4. import RPi.GPIO as GPIO
5. import time
6.
7. def blink(pin):
8.
9. GPIO.output(pin, GPIO.HIGH)
10. time.sleep(2)
11.
12. GPIO.output(pin,GPIO.LOW)
13. time.sleep(2)
14. return
15.
16. GPIO.setmode(GPIO.BOARD)
17. GPIO.setup(11, GPIO.OUT)
18.
19. for i in range(0,5):
20. blink(11)
21.
GPIO.cleanup()
V. Install two different photo/painting programs on your RPI and work with them. Modify an image and create a new one with GIMP. If you have used Photoshop, compare the two. Create a drawing with tux paint. How does it compare with Microsoft Paint?
VI. Install GIMP sudo apt-get update, then the command sudo apt-get install gimp
1. Modify an existing image with GIMP.
2. Create a new image with GIMP.
3. If you have used Photoshop, compare it with GIMP.
4. include both images in your Final Course Project.
VII. Install Tux Paint for a simple drawing program sudo apt-get install tuxpaint
1. Create a simple drawing.
2. Compare the drawing to Paint.
3. Include the image in your Final Course Project.
