TODO

• Components:
  • Buzzer
    • Setup a basic sketch, buzzing
    • Decide on active vs. passive [passive for now]
    • Decide on the best frequency it the buzzer is inside the case [maybe 1k, doesn't seem to matter]
  • Potentiometer
    • Set up a basic sketch, read the values
    • Try reading in increases as a system interrupt
  • Button
    • Set up a basic sketch, digital read the input
    • Try the input as a system interrupt
  • Servo
    • Set up a basic sketch, just get it to turn
    • Set up a method to turn 90 degrees
  • Detecting rapid change
    • Decide on a structure for holding data [linked list is best, but array will be faster]
    • Calculate the averages every cycle? (10sec & 2sec?)
• Combine components:
  • If the fake heart rate is over a threshold set off the buzzer
  • If the buzzer is going off and the button is pressed cancel the injection
• Button abort example:
  • Press button to activate -> wait 1 second -> press button to deactivate
  • Press button to activate -> wait 2 seconds -> inject
• Heart rate example:
  • Show 'heartbeat'
  • Show rolling averages
  • If the short term is too high, audio warning
  • Inject
• Cleanup:
  • Replace the array logic with a LinkedList
  • Add handling for millis overflow at 50 days
• Housekeeping:
  • Add a description to this repo
