No I didn't, I still remember.I gave you an exercise but it seems that you ignored it.
I thought of using photodiode as a part of Voltage divider. Maybe not a good plan.
But I had a problem with saturation. Also I need to exercise with transistors it self. From some example in Books or something. I just need to catch the flow of calculating transistors. Because now I am struggeling with resistors. With photodiode that changes its Voltage can make it a bit harder especially when I can't use Thevenin equivelant like jony did.
