Contents of This Repository

• Arduino Code:
  • DSCPM 2-3/1-2
  • DSCPM 2-2
  • Fluidic Multiplexers
• Python Scripts:
  • Edge-detection scripts for generating volume-infused vs. time and flow rate vs. time plots from pre-cropped horizontal (left-to-right) videos of dyed fluid infusing into micro-bore tubing.
  • Note: Generative AI was utilized in the development of these scripts. The authors have rigorously validated the generated quantitative data against raw video data and assume full responsibility for its accuracy.
• 3D Printable Components:
  • STL files for DSCPM parts.
