Rohan Shenoy’s Weekly Status Report for 3/15/2025

• • Built the circuitry for the electronic solenoid valve and programmed it to iteratively turn on and off
    • Link to video showing valve turning on and off (sound) and circuitry:  https://drive.google.com/file/d/1cYyzbUCx6jC4d_3jghCyST_yZ1O_LXlZ/view?usp=drive_link
  • Drilled holes and attached the tubes to sample bottles to determine appropriate containers to hold our liquids
  •  
  • Mapped Arduino pins to ingredients on the website (fixed for now) so we can scale out and control different valves for different drinks.
    • Link to function where communication between arduino and website occurs: https://github.com/aakinci32/barbelt/blob/dbc9e541826464d9527ecb484b8c9c31bc788d3a/BarBelt/arduino.py#L4
    • Link to mappings: https://github.com/aakinci32/barbelt/blob/dbc9e541826464d9527ecb484b8c9c31bc788d3a/BarBelt/constants.py#L1
  • Tested/Demo flow rate for 1/4 inch diameter tubing (deemed appropriate) to control precise volume of liquid
    • Link to Video showing demo of water flowing in increments through valve:  https://drive.google.com/file/d/1URmfodUijLGzlicqquvTk_xCvq1XVxGO/view?usp=drive_link

Next Week Deliverables

• Scale out to about 5 or 6 drinks using solenoid valves and the appropriate tubing and bottles.
• Figure out how to elevate the wheel holding the bottles to ensure downward flow while ensuring the electronic circuitry is secure
• Map out and experiment time valve is open to volume of liquid dispensed in order to program amount in mL user wants to time valve should stay open
