Hello, I have just finished my Quiztable MK133. It’s the first time I’m doing anything like this, so I’m an absolute beginner. I believe I followed the instructions quite neatly, but of course it does not work and I dont know where to start searching for errors.
When I push the Reset Button, two of the contestants led light up and only for when I keep it pushed. Nothing else reacts when I try pushing Buttons.
I edited the circuit diagram to show which of the led works. The green ones light up when I push the blue button as long as I keep pushing it. The red ones dont light up at all and all other buttons dont seem to work either.
Here are Pictures of the MK aswell. Its my first time soldering at all, so its quite poor.
Maybe someone sees where the soldering is that bad, it has to be done again. Or which of the components could be responsible….
English is not my native language, but I couldnt find any Help in german language. So I hope anybody understands what I’m trying to say, has mercy with my poor soul and will help me
Thanks for any help!
