03/07/23 - Arduino and GSR

• [x] Setup: Git, Notion
• [x] Polygraph:
  • [x] Get data stream in
    • [x] Look at the outputs
    • [x] remap into voltage if in digital form - 0-1023 atm, can be remapped to voltage if needed.
  • [x] Processing and correction
    • [x] Look at libraries that do this
  • [x] Plotting (using serial plotter) - has been effectively pushed
  • [x] motor control output - has been effectively pushed
• [x] Arduino code
  • [x] Connect the polygraph to the person and the Arduino
    • [x] Have a calibration node/function that activates upon start

04/07/23 - Emotibit environment setup and docs exploration

• [x] Set-up complete
• [x] Have a decent understanding

05/07/23 - Emotibit data analysis

Understand the working principle of

• [x] PPG
  • [x] Data interpretation (Already parsed it, Just plotting to be done by Aarushi)
• [x] EDA/GSR
  • [x] Data interpretation
• [x] Temperature sensor
  • [x] Data interpretation
• [x] 9 axis IMU
  • [x] Data interpretation
• [x] Understanding which data stream is more relevant
  • [x] Write the order of it
• [x] Rudimentary code for flagging spikes
  • [x] Method to obtain data from the feather on the go.

Other sensors to work with: @Aarushi Raheja - Discontinued

1. Polar sensor:
2. Exciteometer:

15/07/23 -

• [x] Get the signal out,
• [x] Process the data more efficiently
• [x] Handshake works
• [x] Latency accounted for (175ms for the entire cycle)
