It is an electronic project without programming or any micro controller
you can make your own customized word's led sing board using this circuit
in this project I have used shift resistor IC 74ls164 and IC 555 for animation. you can make led board with 8 letter words
I make in my project "WELCOME " word it is 7 letter word.
All components of this project are available at https://lcsc.com
Step 1: You Need to Make
All parts are available at https://lcsc.com
Parts list -

& 12 volt adapter for power source.
Step 2: Making LED Board
I make in my project "WELCOME " word it is 7 letters word
you can make your own customized word's led sing board using this circuit up to 8 letters words
All led's positive & negative pins are connected with etch other (per letter)
negative pins are goes to collector pin of transistor Positive pins are connected with 680 ohm resistor & all resistors goes to 12 volt positive
if your word are big & you are using more LEDs in per letter then use resistor lower than 680 ohm.
for bigger sign board you can use a separate power supply for led board.
Step 3: Making Controller Board & Joining to LED Board
IC - 74LS164 & IC 555 runs on 5v volt so I used here a 5 voltage regulator IC 7805
Potentiometer 100K connected to pin 6&7 of timer IC 555.you can control animation speed using this Potentiometer
8 piece 547b transistor used for drive the leds & another one transistor 547b for reset pin
now make circuit using circuit diagram on a vero board
after that join transistors collector pin to led board's negative pin of each letter
& join 12 volt positive to led board positive where all 680 ohm resistors is connected.
power it with 12 volt 1 amp dc power adapter.
