hi

so I have a project and the project is to program a home system that would turn on lights and a fan if there are people in the room and turn them off when nobody in the room

detects entrance and exit by two sets of IR emitters and receivers
also, it should display the number of people currently in the room on an LCD screen

the problem is that I have limited knowledge of programming

can anybody help me with programming?

What have you tried so far ?

Have you looked at and experimented with the examples in the IDE ?

Which sensors and LCD do you have ?

Can you read the sensors and display the values on the Serial monitor ?

Can you display fixed text on the LCD ?

Which Arduino board do you have ?

Is this a school or college assignment ?

Just about any 1602 LCD can be driven by the UNO - tutorial. There are serial and parallel options.

Making yourself familiar with the state change detection and debounce examples in the IDE - file/examples/2.digital - will go a long way toward reducing frustration later.
