Hi all,

Trying to build a small LED connected to an arduino that will light up when a laser pointer(cheap one) trigger the sensor. It need to work in day light.

I was wondering if you have any suggestion for what to use?

Thanks

Hello @Shouku and welcome to the RobotShop forum!

You could use a phototransistor and build something similar to this:

Or if you know the frequency your laser pointer has you could use this:

There are other types of photosensors that could work as well but I’m afraid I won’t be able to pick one specific as I haven’t done anything similar, but this might give you some ideas:

Or try checking the Infrared & Light Sensors section of the store.

I hope that helps!

Good luck with your project
