10th week..

for this week, I have worked on settling the receiver circuit for interrupt function for this system. after done the main circuit and the transmitter couple week ago, I have design the receiver after testing it on the project board. in this week also I have updating the report for chapter 3 and 4.

the design of receiver circuit

due to the overlapping signal which occur, I have decided to separated the output for the receiver using the decoder at each of the transmitter like the remote control for alarm.
