Project Title
OVS: Piano Glove
Abstract
Music is in our everyday lives. Unfortunately, it is expensive to learn how to play an instrument. Therefore, we have decided to create Piano Gloves which can stand as a cheaper alternative to purchasing a Piano. This is a device that generates a realistic piano-key note based on which finger is flexed.
Objectives & Introduction
The objective of this project is to create a glove which can produce a specific piano-key note based which finger is flexed. To accomplish this task, we had to do the following:
- Purchase all necessary parts (as seen in the next section below)
- Simulate piano-key notes in MATLAB using the Karplus Strong Algorithm
- Port MATLAB Code to C using RTOS
- Sew Flex Sensors onto Gloves
- Create our own ADC circuit using OP-AMPS to handle 10 Analog inputs (1 per each finger)
- Set up Bluetooth Communication between the SJSUOne board and the Intel Compute Stick
- Create a Real Time visualization based on which finger is flexed
- Perform a full system integration for a finalized product
Team Members & Responsibilities

Schedule Overview
Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Hardware Development
System Block Diagram
The following diagram is a high-level overview of our system. It is depicts the general structure of our design. In addition to that, it also demonstrates a generalization of the major system components that were used as well as their relationship among each other.
Flex Sensors
Schmitt and Trigger
The Schmitt and Trigger circuit is used to convert the Analog Output of the Flex Sensors into a Digital Signal. This Analog to Digital Conversion (ADC) is done so that the SJSUOne MCU can interpret the input signal using a GPIO port.
- Design Choice: We decided to create our own ADC circuit because of the limited availability on the SJSUOne board. There are simply not enough ADC pins to perform our task, as we would need 10 ADC pins.
SJSUOne Board
General Purpose Input/Output (GPIO)
Digital to Analog Converter (DAC)
- Design Choice Trade-Off: Due to time constraints and limited funding, we used the on-board 10-Bit DAC instead of purchasing a 12-Bit module. Since the on-board DAC is 10-Bits, we were only able to get 1K distinct values, as opposed to 4K with a 12-Bit. Therefore the Analog Signal that was output to the Audio Speaker was not as precise as we hoped for.
Intel Compute Stick
PCB Design & Schematic
Datasheets
System Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design & Implementation
Software Schedule
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Integration Testing, Results, & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
Hardware
My Issue #1
- Initially we had ordered the wrong parts. Due to time constraints, we rushed selecting parts and were not careful on selecting the components that had the right packaging. Therefore, we ended up purchasing MSOPs (Mini-Small-Outlined-Package) instead of PDIPs (Plastic Dual Inlined Package). Using MSOPs would not work for us because the IC was simply too small to work with. It would not be able to fit on our breadboard for prototyping purposes.
