Thank you.
As stated in the text: The decoupling capacitors used are 47uF, but any value >= 10uF is OK. https://www.tinytronics.nl/shop/nl/componenten/condensatoren/10uf-50v-elektrolytische-condensator
But the same is for the 220nF capacitor. Any value between 100nf-470nf will do. https://www.tinytronics.nl/shop/nl/componenten/condensatoren/100nf-50v-ceramische-condensator
The resistors 4k7 pull up (anything between 1k-10k) need 2 https://www.tinytronics.nl/shop/nl/componenten/weerstanden/4.7k%CF%89-weerstand
The resistors 22k pull up/down (10k-33k will do). Need 2 https://www.tinytronics.nl/shop/nl/componenten/weerstanden/10k%CF%89-weerstand-(standaard-pull-up-of-pull-down-weerstand)
1K can be replaced by 1k-3k3 to protect input (need 1) https://www.tinytronics.nl/shop/nl/componenten/weerstanden/1k%CF%89-weerstand
Preferable use the same resistor values, just to prevent any problems.
Cheers,
Frank

Great project! But ... could you please check what components (resistors/capacitors) I need for this great piece of hardware? There could be a difference between photo's and your scheme? I'm not that experienced, but nice soldering could be a nice try :)
