[Benti]

Hi guys, I just wanna ask how do I make this circuit work? I cant seem to make the 7 segment work and I can see no errors in my connections. Or do I?

Thanks

The circuit requires a commom anode display.

Hi, thanks for the help. I tried replacing the display with a common cathode but still no luck. Any other ideas?

Check out the attached. The display must be common ANODE.

Hi Ncha,

Your 7 segment LEDS are not connected correctly, if you move the LEDs you will see the problem.
