Findings: 

• Voltage is not the same throughout (indicated by the voltemeters)

• Probes weren't turning on due to the threshold being too high

Plan for next week:

• Use random values that mimic brainwave values (voltage generator in Multisim)

Problem: Can't run tests on Fuion360 because Fusion can't tell what our Vref (voltage reference) is referring to. We must find a way to link all the VREFs together and to reference the same source or system.

Solution / Findings:

• Softwares like Fusion360 have tools called Net Labels and Global Labels that are used to simplify a schematic design when it involves multiple connections to a reference voltage and ensure that all VREFs in our design are linked. 

• Net vs. Global Labels:

  • Net Labels are used to make connections on one page of the schematic (used for simpler designs).

  • Global Labels are used to make connections across a schematic with multiple pages (used in more complex designs). 

• Current solution: 

  • Our team has decided to use Net Labels to link all of the VREFs together to make them reference the same reference voltage. We believe that our schematic design is simple enough to use this instead of Global Labels

• Next Steps: 

  • Learn exactly how to create net labels in Fusion360 on our existing design. 

  • Create the net label and run tests to make sure it is referencing the same voltage. 

Using voltage references from Mr. Rojas' college project, I added them to the algorithm with the simple harmonic motion equation for the first model of the algorithm (simple and basic so we can immediately start testing the circuit). 

• The problem with the scope of this project and my current knowledge in biology and electricity is that I don't have any exact way to calculate or determine the general values for microvoltages in the brain that an electrode would detect. Although no hard work or calculations were involved in this part of the process this week, being given the values allows the group to keep progressing. 

Next Steps:

• Create the angular frequency calculations for values

• Create the MATLAB to Arduino push in Simulink (MATLAB toolbox)
