/** \def DEFINE_HEATER
  Define your heaters and devices here.

  To attach a heater to a temp sensor above, simply use exactly the same
  name - copy+paste is your friend. Some common names are 'extruder',
  'bed', 'fan', 'motor', ... names with special meaning can be found
  in gcode_process.c. Currently, these are:
    HEATER_extruder   (M104)
    HEATER_bed        (M140)
    HEATER_fan        (M106)

  Devices don't neccessarily have a temperature sensor, e.g. fans or
  milling spindles. Operate such devices by setting their power (M106),
  instead of setting their temperature (M104).

  Also note, the index of a heater (M106 P#) can differ from the index of
  its attached temperature sensor (M104 P#) in case sensor-less devices
  are defined or the order of the definitions differs. The first defined
  device has the index 0 (zero).

  Set 'invert' to 0 for normal heaters. Setting it to 1 inverts the pin signal
  for this pin, e.g. for a MOSFET with a driver.

  Set 'pwm' to ...
    1  for using PWM on a PWM-able pin and on/off on other pins.
    0  for using on/off on a PWM-able pin, too.

  Using PWM usually gives smoother temperature control but can conflict
  with slow switches, like solid state relays. PWM frequency can be
  influenced globally with FAST_PWM, see below.
