Acum 35 minute, nel65 a spus:

tiristorul este montat  intre punte si primul condensator de filtraj,nu dupa acel cond...

ASTA am zis si eu...

Dar... sa revin:

Cam asta-i ideea cu display-ul... 2 voltmetre, 2 ampermetre, masuratorile din Arduino, afisarea din arduino, cu conversie serial- paralel+latch in 595, decodoare BCD-7segm pentru...segmente si BCD-zecimal pentru digiti (anozi...) un fel de multiplexare... Mai mult ca sigur mai am nevoie de cate un tranzistor in anodul fiecarui digit, sau macar cate un inversor (NOT gate)...
