This project is using PIC18F4550. PIR sensor is used to sense motion. When there is movement, the data pin of PIR sensor will send high signal to PIC. The PIR sensor is very easy to used with PIC as it send digital HIGH and LOW signal only as active HIGH switch. In this project, when there is movement, LCD will shows "object detected" referring to video below.
**PIR sensor needs atleast 5 minutes to be in ready mode. So, delay must be insert before any other program.
