I started some project and I though I could do it with informations from the internet, but it's pretty tough to do my self.
What i'm stuck on now is that I'll read led light with phototransistor and by using comparator(lm319N), I wanna output 5v when led is on and 0v when led is off.
where can I start this out from? I've seen many comparator circuit, but can't seem to do my self.
Please any help.
