#
# EspHome device that controls the inclination of a bed. Assumes the Esp32
# is connected to a 12V motor via a motor controller with GPIO4 and 5
# connected to the forward and reverse PWM inputs. Also requires an
# ADXL345 accelerometer that is mounted under the bed frame in such a way
# that its tilt angle can be determined based on it becoming "off_vertical".
# This is used to stop the bed motor once the ADXL345 tells this Esp32 the
# bed is inclined as desired. I also have an LCD readout but that is optional.
