Voltmetru ampermetru digital


Recommended Posts

Salutare! Pentru cine vrea o jucarie frumoasa bazata pe arduino, prezint un voltmetru-ampermetru digital facut de mine folosind ca microcontroler o clona de atmega 328p mai exact o clona de arduino nano. Schema, codul si montajul realizat de mine se poate vedea mai jos. Inca nu am testat bine ampermetrul. Iar pentru voltmetru recomand acel potentiometru de 10k sa se foloseasca un potentiometru de precizie, pentru a calibra mai usor voltmetru sa afiseze o tensiune cat mai exacta.
