    How can i make a simple LED initial? i don't need matrix or whatever only 4 letters.
    Will the LEDs lit up for a 12Vdc battery or ... if i just connect them in parallel?
    i estimated that i would need about 20-30 LEDs.
    Do i need resistors or anything else? Anyone can advice me on this?

    Its an easy circuit so i google on it but there were too many results. Anyone can link me to a good website would be appreciated.
