Overview
We wanted to create a board that would essentially simulate an airplane landing as we approach the ground through the use of sensors and mechanical components. This would include an ultrasonic sensor detecting how close we are to the ground, a speaker creating noises as we are approaching the ground, and LED lights that flash depending on our distance as well. When the compostion of the board is complete, it will be planted on a 3D printed plane giving a more immersive landing simulator.
Schematic
In order to power our board, we to have do a step 5V from the our type C USB to 3.3V using a regulator. The USB is useful when needing a serial monitor on a connected computer for debugging on Arduino.
Most of our components are powered through our ESP32, including our ultrasonic sensor, speaker, and LED's. Components such as our regulator and Ultrasonic Sensor required creating footprints.
In terms of making our designs, most were in series with one another, such as our resistors for our LED's and speaker. The only case where it would be different would be the use of a voltage divider for our Ultra Sonic Sensor, where we are working with different voltages once again.

Layout
In terms of our layout, we had to be very technical about where our components would be places in order to maintain the balance of our board. We also had to keep in mind which components would require to be closest to the edges, such as our USB-C and Ultrasonic Sensor. However, due to some of our components requiring to be so close to the edge, this also meant taking into account locations of our mounting holes, which in this case would only be in 3 corners to accomodate for our Ultrasonic Sensor. Below we display each of our copper layers individually, and one together. We decided that since we did not have too many components, we would designate the blue layer for ground and the red for the remainder of the wiring.
Conclusion
Due to outside circumstances, we would not be able to have our full design complete on time for presentation. However, we still have plans to complete the project still when we have all of our parts for the assemblage. To the left would have been an example of a 3D printed design. Below is a better visual of how the theoretical boards would have been.
If we had the time to solder, we would need to solder wires to the USB ports since it was not flushed and wouldn't be able to directly connect. Also we would need to modify the ultrasonic sensor to either be bent downwards so it would be facing the ground, or mount the board vertically with no modifications to the board.
Debugging will come with progress but as of now that is our current game plan. We have learned so much in the course and it was a pleasure taking this class!
