Hi everyone,

I am trying to sync the movement of a candle flame with a 12v light bulbthrough my arduino uno so the lightbulb flickers just as the candle does.
i have been recommended to get LDR's
I am looking for a place online to buy LDR's to detect candle light movement , i dont have much knowledge on a good type of LDR or place to source them.

Could anyone suggest a place to get them or even if they are the right thing to use maybe even suggestions for other sensors.

Thanks.

In theory there is no difference between theory and practice, however in practice there are many...

You asked (almost) the same question earlier...  Why start a new discussion?

I know it is another question - but it is just very related to your project...

Which country are you from?
eBay is often cheapest but delivery times can be months.
Regular shops like sparkfun have almost overnight delivery (depending on country again) for a bit higher price.

In the Netherlands there are shops that ask 4Euro for delivery and some ask 15Euro, so there is a big diff. I need to say there is def. diff in quality of service too.

What is your definition of a good deal?

Here is an Ebay link for 10 of the devices that should work well...
