Yesterday ive finished the interface.
But the LEDs are not as nice as i want em to have. It is stupid, i know, but i want to use some blue more powerful leds.
My multimeter got damaged and my new one will arrive hopefully next weak, can anybody pls tell me the voltage incoming before the resistors?
Thanks a lot for help and sry for bad english only german school knowledge.
