Hello everyone,
L'm using PIC16F876A to output binary 1 at PORTC.1. My idea is to trigger an electronic doorlock which needs 12v. I used ULN2003A between the PIC and the doorlock, but the output voltage of the PIC (2.2V) of PORTC.1 could not trigger the ULN2003A to output the 12V because it requires input of 5V . Please give me alternative solutions for my purpose.


Thanks in advance,
Joe
