# This is a fan speed control utility tool for user to customize fan speed.
# Priciple: send speed argument to the MCU
# Technical Part
# There are four arguments:
# pwm_025 means sending 25% PWM signal to MCU. The fan will run at 25% speed level.
# pwm_050 means sending 50% PWM signal to MCU. The fan will run at 50% speed level.
# pwm_075 means sending 75% PWM signal to MCU. The fan will run at 75% speed level.
# pwm_100 means sending 100% PWM signal to MCU.The fan will run at 100% speed level.
#
# This is the serial port that connect to deskPi mainboard and it will
# communicate with Raspberry Pi and get the signal for fan speed adjusting.

values of different speeds parameters(for example 25, 50, 75, 100, this is the default
