Hi
Sorry my english is not the best i tried to built a input output interface for an arcade game to handle coin impulses
8 button ins normally pulled up
1 output to an reed reelay
and 6 optocoupler in
1 old display 128 x 32
sometimes the system freeze also when nothing happened no pressed buttons
it is connected to 12V PSU
thank you tom
