Week 8

What was accomplished?

Goal: Start testing with the physical circuit and in Fusion360. Wrap up any online tests
- Allison: Learn how to manufacture and physically build a PCB on the CNC machines at school.
- Samantha: Finish the testing documents and test the circuit with Claire
- Claire: See signals, even if it is just one, with the oscilloscope.
Team accomplishment:
- Samantha: Finished her portion of the testing document. Created testing sections and began preparing them for testing with MATLAB.
- Allison: Tested and began learning how to manufacture a PCB using the CNC machine.
- Claire: Obtained real connection and voltage values between the Arduino and Simulink (in MATLAB).

W8- Weekly Report

Progress:
- Tested drilling using the CNC machine
  - troubleshooted and arrived at using a leveling tool on the copper plate with the plate at the center to prrevent it from breaking the drill bit.
  - Began testing sizes of traces.
Plan for next week:
- construct dummy pcb with modifications found during testing
  - seal pcb if parts arrive

Multimeter Test.mp4

Findings / Progress:
- Arduino Hardware Explorer is an unreliable source for checking the Simulink, generated values.
- 'uint16' block helps minimize having to translate the raw, electrode data into any specific data type that MATLAB necessitates.
- The connection between the arduino and Simulink model is now established, the multimeter proves it.
Plan for next week:
- Adjust the code to account for the voltage cap of 4.7 volts for the data type of 4095 for the 12-bit DAC.
- Figure out what needs to be added to the model so that the MATLAB function block script runs smoothly and in real time.

Lead: Samantha for documentation and operation | Claire for overall design and goals

Breadboard Testing Procedure

Goal: See signals (just one for this week) on the oscilloscope
Findings / Progress:
- The testing document was reformatted for clarity.
- Pre-testing was started and 3 testing sections have been created so far.
Plan for next week:
- Complete Pre-test
- Finish creating testing sections +prep them
- Begin testing the breadboard once MATLAB is sorted
