final project presentations
Week 19 Overview
This week we're presenting our final projects.
Here's a video of the final piece in action
Main Elements of the Project
- An enclosure to house the components of the installation (eg. electronics & speakers)
- A control panel for user input with 4 buttons to change from different wave forms being output (sine, square, triangle, sawtooth) and include a potentiometer so the user can change the frequency of the wave.
- A shield for an arduino with a DAC chip on it
- A program to handle the inputs and outputs of the system
If I were making it again a few changes I'd make:
- A visual output to see the frequency being output, maybe with an LCD screen.
- When you change from a wave at the moment the frequency isn't the same. I would change this.
- There is an amp on the speakers I used but I think I'd add an amp to the circuit if I was doing it again.
- I would buy speakers and build a dedicated enclosure so I could have this permanently. It would be nice to use this for school groups or in museums workshops
- it would have been impossible to carry out this project without an oscilloscope. Just a note for anyone who's thinking of doing this type of project in the future.
