PR9B : Need help with the schematic diagram

[Jenisme22]

Hi all,

I'm planning to do this project for my college's mini project. however, i need help to combine all the schematic diagram.
I'm afraid i'll combine the schematic wrongly and the whole project couldn't work. So can anyone help me with it?
I would be really really thankful if you guys could help me out, thanks!

You can also email me. this is my email add: Jenny_baby13@hotmail.com

My advice is try to make your key control alarm system working first before you add any extra circuits onto it. Or else your project would become too complicated to debug or troubleshoot.

You can also try simulating them in simulation software such as proteus or multisim
