Big 12v 7 Segment Display
« on: February 04, 2011, 02:31:56 PM »
Hello po,

May project po kasi ako na 50pcs display ng 7segment display,ung 7 segment display is 12v.Driver ko is uln2803 sa pagcontroll ng each segment.Ang tanong ko po is kelangan po ba ng transistor sa common(positive) ng 7segment display ko? kasi 5v po yung MCU ko(PIC16f877).Kelangan po bang magkahiwalay ang supply nila?

Thanks!
