The MODE button is used to switch between manual mode or automatic mode. The mode
will be displayed on the 1602 LCD for 1s when switching. It will be shown in the serial motor
as well.
In automatic mode, if the temperature is higher than the value of Temp_maxlimit, the motor
and fan will start working. They will not stop until the temperature is lower than the value of
Temp_minlimit.
In manual mode, the motor and fan can only be controlled by the APP Click "ON" and "OFF"
to make the motor work or not.
Note:
1. Don't keep the motor working for a long time to prevent L9110 over heat.
2. If the time shown on the 1602 LCD is wrong, please open the file calibration-clock under
the file of lesson33. Then download Calibration_clock.ino to check the time. Next, re-compile
and download the code of lesson 33, you can get the right time.
