Semi automatic moving roof / Nur Suziyana Mohamed Hazaruddin & Nurul Fara Nabila Mat Yunus

Nowadays, environmental pollution gets from bad to worse. Acid rams and global warming are the main concern for us to build this project because these phenomena are dangerous for human and things since it may cause health problems to human and destruction of things. Houses that are situated near industrial areas are more risky as compare to houses that are situated in rural areas as they are more expose to pollution. Thus, Semi-Automatic Moving Roof (SAMR) is a product that eases people to enjoy outdoor activities without worrying about the weather. The methods of designing this project are by doing some observations and analysis about moving roof The first process of this project is to design hardware for SAMR. Secondly, a program is built for SAMR using microcontroller PIC16F84A. Thirdly, the developed circuit is simulated by using Proteus software. Then, a prototype of SAMR is created. Lastly, the process of troubleshooting the software and hardware for SAMR is made. Based on our findings, the SAMR can choose to be operating in manual or in automatic by pressing the selection switch. When the selection switch is in open mode, the SAMR is operating manually by switching on and off another switch and if the selection switch is in close mode, the SAMR is operating automatically by sensing the rain using a rain sensor. The 7-Segment Display will appear number 2 if the SAMR functioning in manual condition while number 1 is displayed when SAMR operates in automatic condition. The DC motors rotate in forward direction and green LEDs turned on when the switch is pressed on or when the rain sensor detects rain. Once the switched is off and the rain sensor does not detect rain, the DC motors rotate in reverse direction and red LEDs turned on
