Hi guys, Last week, I started building this voltmeter circuit:

http://electronics-diy.com/ICL7107_volt_meter.php

Today, i found out that the circuit is made for a MAN6910. My problem is that i accidently bought MAN6740. In short, cathode is anode and vice versa, thats the only difference between the two MAN's. I know, this is perhaps too much asked but ive now spent 2-3 hours and cannot come up with the correct circuit modified to accomodate the MAN6740. I would appriciate it extremely if someone could help me. Or is it impossible?

 

You can uses PNP transistors on the ICL7107 and MAN6740

 

How would that be possible? Where would i have to implement them in the circuit, how many and of what type?

Thanks in advance

 

Each segment would require one transistor, 23 in all. May be better to buy the proper LEDs
