I am trying to implement 30 LED charlieplexing using 6 uC pins. But I am facing problems. There are 5 columns and 6 rows. When I try to glow one led in a particular row then 3 or 4 leds of that glow including/excluding the led which was supposed to glow. Please suggest something to resolve this erratic behaviour of Charlieplexing. I have to give gift to my girlfriend on Valentine's. So please help. I have also tried this thing with smaller version of this (6 leds) but got no success.

Thanks in advance.

Regards,
