Downloaded applicable Arduino IDE’s and software to begin hardware testing with the previous and new Arduinos.
Started doing research on signal conditioning circuits.
Next Week’s Goals:
Continue researching signal conditioning circuits and determine what components would be needed to implement this.
Begin looking into whether or not power factor can be calculated with our current setup.

This Week’s Progress:
Continued research in regard to power factor complications.
Decided to logically implement phase detection within Arduino code, rather than adding hardware.
Added the new Arduino Nano and recognized sensing issues.
Next Week’s Goals:
Determine whether to use a sinusoidal phase detector or a zero-crossing detector.
Attempt to correct the current and voltage measurements through collaboration with the software team.

This Week’s Progress:
Continued troubleshooting the discrepancies in voltage and current measurement through our Arduino code. We began isolating components to remove any additional noise and measured current directly from our current sensor with an oscilloscope to validate the sampling code.
It’s been a bit slow on the research side of things. The next step was going to be discussing my theory and application with a professor to get feedback and suggestions. However, they had a family emergency and will not be available for the next couple weeks, so I will need to change plans a bit.
Next Week’s Goals:
Be able to properly and accurately measure current with our new setup.
Ideally, I would like to have a rough blueprint for phase detection to provide to my team, whether that’s a schematic, written code, etc.
I will sit down with my team to dissect the integration of my proposal and begin looking into C++ conversion.

This Week’s Progress:
Setup our old circuit (with the Arduino Uno) and code to gather data points in voltage and current measurements. Now, we can adequately determine whether or not we are getting more accurate readings.
Plotted said data points and analyzed margin of error, then discussed a realistic goal of accuracy for our new system with a team member.
Worked with a team member to correct our code and begin accurately measuring voltage!!! (I feel super proud of this one.)
Set up a meeting with a professor to finally discuss the implementation of power factor into our code.
Next Week’s Goals:
Go to meeting with professor to discuss the research I’ve done so far and gain feedback.
Start collecting data points from our current setup to begin comparing to old setup.
Share next steps for operation power factor with teammates.
