1. ECE 4330 Project Proposal 1 Motor Music Presentation by Nick Hermanson

2. Overview The motor used in labs 6 through 8 generates a tone based on its RPM. This tone can be used to create simple music, perhaps akin to the music used by ‘8-bit’ video game systems such as the original Nintendo Entertainment System.

3. Hardware The hardware required for this project is included in the kit provided by the class. Other hardware pieces include resistors provided in the lab in ENG 229. The following pieces are expected to be used: Motor NTE3100 optical sensor External LED

4. Hardware (continued) The circuit from lab 8 will be used. The external LED will be added for a heartbeat ‘mode’ signal, as the 8 LED’s built onto the STK500 will be used by the program. No other modifications are expected, but some adjustments may be discovered to be required during the project.

5. Software The basic software used will integrate the code from Lab 8 for proportional closed-loop feedback for the motor’s RPM. This project will add to Lab 8 a table of frequency values for various notes. At least one octave will be recorded in this way. The software will go through a short initialization step, followed by a mode selection state. At least two modes will be implemented.

6. Software (continued) Mode 1: Using the switches on the STK500, the user should be able to press a button and receive a desired tone, allowing the user to compose or play their own music. Modes 2-8: As time permits, at least one basic piece of music will be coded into the program, allowing the user to request it be played at the push of a button while setting the mode of the program. The first piece of music that comes to mind to attempt is the Imperial March from Star Wars.

7. Potential Problems. It is possible that the motor will vary enough that the tones do not come out as desired. It is also possible that the motor will not adjust as desired for crisp notes. Due to the motor, there will be no real capability for smooth note transition, all notes will have to be separated and distinct, a trait known as ‘staccato’ to musicians.
