555 je zapojen zvláštně, to by v reálu zlobilo. Rezistory by měly být stejné 721 kΩ a k R2 (nad kondenzátorem) paralelně dioda s katodou dolu, tím vznikne střída kolem 50%, která čítačům lépe vyhovuje. Jinak pro ochranu dekodéru bych LED připojil přes tranzistory s rezistorem na bázi … Jinak hračička O.K.
