This week, my team and I presented our interim demo, which we prepared as an interactive way to show our progress. I wrote code to demonstrate the DMX transmitter and controller input by using faders (potentiometers) to send signals from the Arduino to an existing light, showing control of color and brightness. For verification, I confirmed the DMX receiver works by scoping both the input and output signals to check for correct transmission and timing.
As I worked on this, I focused on verifying my subsystem by making sure controller inputs map correctly to DMX values and produce the expected lighting outputs. I also used the oscilloscope to check signal consistency. Going forward, I plan to expand this testing to additional controls like pan, tilt, and focus, and check for accuracy and any noticeable delay.
For validation, we plan to test the full system by checking that the light responds correctly to all controller inputs for color and movement. We will compare expected vs. actual behavior, verify motion ranges, and observe responsiveness to ensure the system meets our design goals and works as intended for a user.
Additionally, our group continued fabrication by laser cutting the first rendition of our controller housing and soldering any components we can at this point. I plan to add more inputs and integrate the motor code with the DMX receiver soon. According to our Gantt chart, I am currently on schedule.
