Setup sensors

main control loop
	check all sensors
		read temperatures
		read pressure
		read board inputs
		verify nothing is urgently wrong (Temp/pressure above cutoff)
		set sensor data (in memory)
	read all inputs
		verify nothing is urgently wrong (E-stop)
	get current state
		if changed & dirty
			call previousState.leaveState
		if changed & clean
			call currentState.enterState
	set power LEDs
	
	if state is:
		Startup -- not handling this as a separate state...
			EnterStartup:
				Display welcome
				Verify sensors and pins
				Flash all LEDs
				Set state to input selected state
				verify set all relays off
			ExitStartup:
				continue
		Setup
			EnterSetup:
				set min/max pot values (maybe just hardcoded)
					min temp 120, max temp 200
					min time 10 max time 60
					max pressure 90psi
				verify set all relays off
			ExitSetup:
				Display profile ID
				Confirm save?
				Green - yes, red - no
				hold dirty state until response
			SaveSetup:
				Grab pots values, save to db
				use switches to set profile mode
			InStartup:
				Display Pots readings
		Manual
			EnterManual:
				record run number & start time
			ExitManual:
				turn off all relays
				update run metadata
			InManual:
				Set relays according to switches
				Display Temps & pressure
				Record temps & pressure
		Automatic
			EnterAutomatic:
				Set auto-state to Initializing
			ExitAutomatic:
				Verify state != running
				if running, hold in dirty state
			InAutomatic:
				Initializing
					prompt for select run profile
					wait for green button press
				Starting
					pressurize bladders
					record run start time, profile (persist in log format so if profile changes in the future we still have record of exact run parameters)
					if red button pressed, log and skip to finished/stopped
					if necessary, prompt to set overrides to auto
					await green button press (allow for pressure override)
				Running
					take profile parameters and run to spec
					set relay indicator leds
						cold, good, hot
					log temperature/pressure
					check for manual override (off/auto/on)
					if red button pressed, log and skip to finished/stopped
				Finished/Stopped
					turn off heat relays
					vent air until pressure is down
					green button press loops back to Initializing
		Error
			EnterError:
				turn on error light
				turn off all relays(unless pressure issue, then open relief valve)
				Display message
			ExitError:
				hold dirty until reset button press
			InError:
				blink error light
