PROJECT: Simple Simon Says (SSS1)

OBJECTIVE

Create circuitry and code software to eventually craft a simple version of the classic “Simon” game of recalled repetition.

GRABIT

To assist with consistency across all implementations, data files for use with this project are available on lab46 via the grabit tool. Be sure to obtain it and ensure your implementation properly works with the provided data.

lab46:~/src/SEMESTER/DESIG$ grabit DESIG PROJECT

OVERVIEW

Your task is further expand upon your buzzer circuit by:

  • potentially adding additional sound channels (using multiple passive buzzer circuits). This might involve borrowing buzzers from neighbors when it comes time for your performance
  • potentially adding in one or more buttons that somehow influence the behaviour of the end result (play a different song? Alter quality of notes played somehow?)
  • utilizing LEDs to have a corresponding visual lightshow going along with whatever sound is being produced
  • in your program, use an array to store the individual frequencies to be played, followed by a delay
  • aiming for a more complete song, not just a demonstrative snippet

Contributing to project documentation is also a core part of this project. If from reading the existing documentation or through your own exploring, you find something lacking, unclear, or outright missing, that is an opportunity to potentially contribute content.

You want the project documentation to provide you (as if coming in with no awareness of the project) with sufficient information so as to allow you to proceed. Asking questions on the discord is a great way of getting more information that you can use to add content.

EDIT

You will want to go here to edit and fill in the various sections of the document:

WIRINGPI REVIEW

Remember to set pins used to output mode.

pinMode (pin[X], OUTPUT);

pin[X] is assuming you have a pin array set up.

PINMODE

DIGITALWRITE

From the function name we can assume that it writes some value, and this value will be in the form of 0 and 1. In other words we can say that this function is mainly used to control any device attached to the Pi by assigning value to the pin to which that respective device is attached. For using this function, we have to follow the syntax given below:

digitalWrite(pin, value); To use the digitalWrite() function we need to give it two arguments that are:

Pin: The digital pin number on which the device is connected

Value: the value that is to be assigned to the pin either HIGH or LOW

DIGITALREAD

digitalRead Reads the value from a specified digital pin, either HIGH or LOW. It's syntax reads “ digitalRead(pin) ”.

DELAY

NOTES/FREQUENCIES

In this project and in the last project we have had to use the frequencies of different notes to put together a song. A frequency is what determines the pitch of a sound. A note is used to represent the pitch and duration of a sound in musical notation. From the notes that are found on pieces of sheet music they need to be converted to a certain frequency to match the original sound of the song. This can be solved with note frequency charts, showing the differentiation between octaves.

 

SUBMISSION

To be successful in this project, the following criteria (or their equivalent) must be met:

  • Project must be submit on time, by the deadline.
    • Late submissions will lose 33% credit per day, with the submission window closing on the 3rd day following the deadline.
  • All code must compile cleanly (no warnings or errors)
    • Compile with the -Wall and –std=gnu18 compiler flags
    • all requested functionality must conform to stated requirements (either on this document or in a comment banner in source code files themselves).
  • Executed programs must display in a manner similar to provided output
    • output formatted, where applicable, must match that of project requirements
  • Processing must be correct based on input given and output requested
  • Output, if applicable, must be correct based on values input
  • Code must be nicely and consistently indented
  • Code must be consistently written, to strive for readability from having a consistent style throughout
  • Code must be commented
    • Any “to be implemented” comments MUST be removed
      • these “to be implemented” comments, if still present at evaluation time, will result in points being deducted.
      • Sufficient comments explaining the point of provided logic MUST be present
  • No global variables (without instructor approval), no goto statements, no calling of main()!
  • Track/version the source code in your lab46 semester repository
  • Submit a copy of your source code to me using the submit tool (make submit on lab46 will do this) by the deadline.

Submit Tool Usage

Let's say you have completed work on the project, and are ready to submit, you would do the following:

lab46:~/src/SEMESTER/DESIG/PROJECT$ make submit

You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches.

RUBRIC

I'll be evaluating the project based on the following criteria:

91:sss1:final tally of results (91/91)
*:sss0:used grabit to obtain project by the Sunday prior to duedate [13/13]
*:sss1:picture of unpowered circuit to #desig for approval [13/13]
*:sss1:show me or video of circuit to #desig showing results [13/13]
*:sss1:clean compile, no compiler messages [7/7]
*:sss1:program conforms to project specifications [32/32]
*:sss1:code tracked in lab46 semester repo [13/13]

Pertaining to the collaborative authoring of project documentation

  • each class member is to participate in the contribution of relevant information and formatting of the documentation
    • minimal member contributions consist of:
      • near the class average edits (a value of at least four productive edits)
      • near the average class content change average (a value of at least 256 bytes (absolute value of data content change))
      • near the class content contribution average (a value of at least 1kiB)
      • no adding in one commit then later removing in its entirety for the sake of satisfying edit requirements
    • adding and formatting data in an organized fashion, aiming to create an informative and readable document that anyone in the class can reference
    • content contributions will be factored into a documentation coefficient, a value multiplied against your actual project submission to influence the end result:
      • no contributions, co-efficient is 0.50
      • less than minimum contributions is 0.75
      • met minimum contribution threshold is 1.00

Additionally

  • Solutions not abiding by spirit of project will be subject to a 50% overall deduction
  • Solutions not utilizing descriptive why and how comments will be subject to a 25% overall deduction
  • Solutions not utilizing indentation to promote scope and clarity or otherwise maintaining consistency in code style and presentation will be subject to a 25% overall deduction
  • Solutions not organized and easy to read (assume a terminal at least 90 characters wide, 40 characters tall) are subject to a 25% overall deduction
