Use

Two rows of needle probe input interfaces to meet a variety of resistive sensors (eg light-sensitive resistors, thermistors, etc.), internal 10 k pull the divided voltage sensor input comparator, adjustable resistor voltage comparator negative internal controls comparing the input voltage, the output from the comparison result (positive terminal voltage is higher than the negative terminal, the output is 1, and 0 otherwise).
SCM any IO port output (depending on process definition) connected to a low level of change is detected by the microcontroller to detect changes in ambient brightness.
Analog output AO small plates can be connected to the input voltage acquisition.
