Answer:
Magic eye can be used as automatic guest indicator in your home. Just install this at the bottom of the door and whenever a person would arrive, his shadow will fall on the circuit giving an indication that somebody is present on the door without the knowledge of the visitor. It can also used as a prevention measure against vandalism. So, apart from homes, it can also be used shop and banks. This circuit is based on popularly known hexa inverter IC CD4011, LDR and a few more components.
The magic eye circuit is based on NOT gate CD4049 IC. In this circuit, we are utilizing only 1 gate of IC. To understand the working you should know about the truth table of NOT gate which is:
INPUT
OUTPUT
0
1
1
0
In NOT gate, we will get output as logic high when logic zero is provided and we will get logic zero when logic1 is provided in input.
