Hi jayanth,
I am very greatful for your help and it would be appreciated if you will still help me on this.
With your comment in the 2 switches, it wont get low since I used a common anode LED in it. The 2 switches run smoothly.
Actually, in reality, I am doing a set of LEDs here and not seven segment. But I used the technology of seven segment here so it would be easy for me to program or re-program the micro-controller. The microcontroller is responsible for animating the LEDs here. It's just that I'm having problem with cascading the numbers whenever 0 is reached. This must be like a real scoreboard. Your help is much need here. Thanks in advance.
