Use the 4 switches to control the 4 LEDs. Only 1 clock 1 data signal is needed. Imagine there is a counter on sender and receiver side. The circuit works now thanks to Robert_Kidd.

It’s a bit difficult to trace your circuit. Check that all gate outputs are not overloaded - they are 5V working so won’t like just a diode as a load. Ensure you don’t have gate outputs in parallel - they will fight each other if outputs are at different levels. Sorry I can’t help more at the moment but it is difficult to follow with all the different coloured links.

Thanks for the tip. I tried to arrange everything very systematically, because an understandable arrangement is unfortunately not possible on this board size. Unfortunately some color coded connectors look the same, although they belong to different groups, which can be seen when they are marked. Limiting the number of components to the current quantity and doubling the board size would help me a lot. Do you mean that, between 2 AND gates an additional resistor is needed? Actually I only added all the diodes to suppress reverse flows. Maybe I missed a spot somewhere, just where?

Exactly the problem, very hard to follow with any confidence. Do you have a full circuit I can see?

Your Idea on mux demux and flipflops fixed the problem :) still a bit laggy but at least switching now correct
