it will be better if you put it outside of the fridge. maybe on top of the fridge and use another way to block the senser (Like some place of wood and glue it on the door or something) I'm not the electronics guy but some white block that you use it seem not perminet, if you just make it more beginner friendly it will be good. keep up the good work just think a bit more :3

Nice idea
How many second is the delay of the alarm after opening it..?
Very nice video
Great video
If I used 0.1uF electrolytic capacitor instead of ceramic, would it effect the working circuit?
Is 100 ohms resistor can replace ith other???
if i used smaller ldr will it affect my circuit?
Baity Wahidiah no it does not effect ...you can tune its resistance with potentiometer
Baity Wahidiah .. nak no telefon wei ..
Can I know the purpose of doing this and use of it please
It's for small kid ....who opens the door and left it
