Automatic stairs led lighting arduino shield

Re: Automatic stairs led lighting arduino shield
Hi @aivaredze
Could you help to detail the hardware specification such as: LED Strip, Power Supply Switch and what is the device which shown on top of 2 PIR sensor?

thanks,
Boly

Leds 12v 2.5A max per strip
Power supply: 12v and multiply the number of strips buy the max current they use to get the minimum output current for the power supply
The top right component is a photo resistor used to measure how much light is in the room, so you don't turn on the stairs lights during the day

Thanks gohan, it is clear. How can I search the light resistor in ebay? do you have name or keyword to search?

@Chen-Boly

Have you tried searching for "light resistor"? Or perhaps "Light resistor arduino" ? ;)

Light resistor arduino

Thanks Tbowmo, it is this one?

@Chen-Boly

Yes, that's the one..

@tbowmo
it has a different type (different number), any type is ok, right?

[tbowmo]

probably another manufacturer.. But I would go with this one..
