In this project, I define the simple protocol in which a laser was emitted in LDR sensor and we get an red light and buzzer was opened but whenever the light was disturbed from emitting on a diode. the buzzer on and a green light was on.
After that I will work on the next level of security, so you can get other details or can say advance detail was shared on next with video with some code was also provided.
You can copy the code from here and with any further changes make it a running project.
