hey everyone,hope you are doing fine.

First of all MERRY CHRISTMAS & HAPPY NEW YEAR to all of you

here in this video i am going to make a 24x6 LED scrolling text display board using Arduino nano,3-74hc595 shift resistors and 1-CD 4017 decade counter.

I have made this project using 144 bright blue LEDs to make a board of 24X6 dimension...you can make any size you want but for that you have to change the code....but connection of the ICs to the anode and cathode lines of the LEDs will remain same.


Things needed to make this 24x6 LED scrolling text display board :-
1) 1x perforated board
2) 144x Bright blue LEDs
3) 1x Arduino NANO
4) 1x HC-05 Bluetooth module
5) 3x 74HC595
6) 1x CD4017
7) 6x 2N3904
8) 24x 100E resistor
9) 6x 1k ohm resistor
10) 1x 40 pin female berge connector
11) 1x DC jack
12) 4x nut bolts
