class SpectraSoftPot < ArduinoSketch
# demonstrate capability to use soft pot as traditional pot
# the last pot reading remains "locked" to the last touch point
# similar same behavior as ipod
#
# this sketch assumes a pa_lcd operating at 19200 and one
# spectra symbol softpot connected to analog pin 3
#
output_pin 5, :as => :my_lcd, :device => :pa_lcd, :rate => 19200, :clear_screen => :true
input_pin 3, :as => :sensor_one, :device => :spectra
def setup
delay 1000
my_lcd.setxy 0,0, "spectra symbol"
my_lcd.setxy 0,1, "soft pot"
delay 5000

def loop
my_lcd.setxy 0,1
# since lcd's have issues clearing tens and hundreds digits when reading ones,
# we use pad_int_to_str, which is a hack to display these cleanly
# pad_int_to_str takes two arguments: an integer and the final string length
#
my_lcd.print pad_int_to_str sensor_one.soft_lock, 3
