hi,
i made 4 inch 4 digit comman anode display with microcontroller. i got the error in decimal point.
when i set low from microcontroller than decimal point is glow. but when i give high than also its glow.
i gave 12V for drive 4 inch seven segment display.
There is 50 ohm Resistor on all A,B,C,D,E,F,G AND DP line.
How can i overcome these problem???
