Thank you Mr. Surender for your reply.
Bi-color LEDs proposed to use are RED-GREEN, by making it ON both the LEDs at a time, will produce Orange color. I think color combinations may not be a problem. I sen some where in the internet that 3 Digit 7 Segment LED Displays are available, but the thing is all seven pins of each digit are parallelly connected i.e. A,B,C,D,E,F, G segments of all 3 digits are connected paralelly and common cathode pins of each digit are separately connectable. If 3 Digit display is not available, I can use 3 single digit bi-color 7 Segment displays.
But, I don't know about LED Driver. Can you guide me.
Thank you,

Thank you Mr. Rahul Siva. I want 4 sets i.e. 4 timers run together with one microcontroller. And for 8051, writing a program is OK. How to implement i.e. burning into IC and other associated circuit etc. Arduino Uno microcontroller board is readily available and we can write a program in PC and can be loaded using USB cable with arduino software which is freely available. Is 8051 kits are also available like this?
Please guide me.
Thank you
