    I am designing a circuit that will take numbers from keypad and then lit up leds/bits which are associated to that number which should previously stored against that number
    eg if i enter 1234 it switch on led x,y,z
    Its kind of electronic password but not exactly because i want inputs and then use the memory to lit up the related leds.
    Can anyone guide please whats the best equipment,software and language i should use

    I hope that make sense.

    You could start with something like an Arduino.

    Keypads to go with the Arduino can be had from Ebay for a couple of dollars.
    Flexible membrane with a short connection tail.
    Many examples for the code on Google or better still, do some reading and "roll your own" as you will learn more that way.
    Arduino forum will not write your code for you but are very helpful getting you on the right track.
    Correct grammar is essential in programming so proof read your code, it catches many every day.
