Continues with the previous works...the problem now is how to fix and combine the X-10 protocol and the PIC16F877A...after i ask people that expert with programmer..i found the solution which is try to avoid use the X-10 protocol...the PIC microcontroller will control directly all the devices in house...since we not use X-10..we recommended to add another application in this project...we suggest to add security system control with PIC...the input will use a keypad that we can key-in the password to open the door.....i had identify the component used to construct the security system...we had to use 3 sensor (motion sensor, vibration sensor and door sensor)... for the program, the visual basic will function as ON/OFF AC devices and as a monitor security system..
Here is the new block diagram for the add application on this project..
