  # Photo diode pulse meter example (Glow meter)
  # This configuration requires the ${digi_pot_pin} output to be configured
  # The digital potentiometer defaults to an output value of ~1.5v
  # The photo diode circuit will conduct and drop below the reference when photons are absorbed.
  # You should set the digital voltage to be around the mid point of this voltage drop.
  # There is no need to measure it since if it's set to low or to high it stops detecting the pulse.
  # Once the range is known for example 120-140 then set it to 130 which is the mid point.
  # Not setting at the midpoint will cause significant false counts do to reading noise near the comparator threshhold.
