Buna ziua,Vreau sa scriu "service auto" pe un panou si as vrea sa pun leduri pe marginea scrisului.As vrea o schema care sa comand ledurile,un joc de lumini ,sa se aprinda cate o litera pe rand pana se aprind toate,sa stea un timp aprins tot scrisul si pe urma de la capat.Cu stima,Ovidiu

cu cateva modificari cred ca se poate folosi o schema cu doua cd4017 "in cascada" :

mult mai simplu ar fi o varianta cu microcontroller dar nu ma descurc in ceea ce priveste programarea acestora ,asadar nu-ti pot face o recomandare in acest sens; poate te ajuta altcineva...
