i'm making this home automation system for my year final project. I thought it would be easy to code this entire thing but i was wrong 
! dont know how to proceed further .
there are two ir sensors, 1 temp sensor , and a photo resistor.
it should start an allarm and also a led should start blinking ir the ir sensor detects something , the leds should get ON if photoresistor is in low light , and finally a motor should get started if temperature is too high. And all this gets in action if a button is pushed. im attaching the program i made. its not finished yet ! dont know how to proceed further:(
