Title: human detect counter with UVC light as sanitizing. Use 2 infrared sensors, 2 LEDS, 1 UVC light. Write the code about ARM-Cortex M3 STM32F103C8 with condition below:

-infrared sensors is used to detect/count the number of human

-When a human enters a mall, the counter increase 1 and the LCD will show the latest number of human inside the mall.

-When no human in mall, the counter will decrease by 1 and the LCD will show the latest number of human inside the mall.

-GREEN LED ON: still can enter & no. of human below 20 pax -RED LED ON: cannot enter anymore & no. of human exceeds 20 pax & UVC light on

A1=infraredsensor1, A2=infraredsensor2, B3=green LED, B4=red LED, B5=UVClight
