# crazy experiment in progress
# purpose
#
# retain last reading after finger is removed from spectrasymbol
# soft pot
#
# use
# two steps
#
# one
# declare :device => :sensor
# example:
# input_pin 1, :as => :sensor_one, :device => :spectra
#
# two
# instead of:
# my_lcd.print analogRead sensor_two
# use soft_lock
# my_lcd.print sensor_one.spectra_lock
#
#
# notes:
# experimental settings for 100mm spectrasymbol
#
# hysteresis is set at 5
# amount of sensor drop is set to 3
# delay time (dtime) is 4
# cutoff set to 10
