I bought a small flame photodiode for a robot Im currently working on. Being a "flame" photodiode I thought it would ignore most light and pretty much only output whenever it gets light from a flame but it seems normal day light can set it off. Even lamps or sealing lights seem to be enough for it.
Pretty much almost makes it a reguarl photodiode.
I can get the data from it with this line of code: FlameValue=analogRead(0);
Just read the analog pin.
Anyway I can maybe fine tune it better for flames?
