So what are you waiting for? Get those LEDs out and heat up your soldering iron because we are about to make a 24X6 LED matrix!

Signing UpStep 1: Getting All The Right Things
For the matrix you will:
1. 144 LEDs
2. 24 resistors( The value is determent by the type of LEDs, in my case 91 ohm)
3. 4017 decade counter
4. 6 1KOhm resistors
5. 6 2N3904 transistors
6. A long Perfboard
7. Arduino
8. 3 x 74HC595 shift register
10. some pin headers

up,down:
ROW down to up (ROW1 go to ROW6 and ROW6 go to ROW1 and so on...) will turn your "image"
change the orientation of text:
COL1 to COL24 and COL24 to COL1 and so on...

You can find another projects based on LED at here
1.int latchPinPORTB = latchPin - 8;
2.int clockPinPORTB = clockPin - 8;
3.int dataPinPORTB = dataPin - 8;
what I want to ask (- 8) was from where ..?
sorry, my question, please understand because I am still in the stage of to learn,thank's
Thank you.
And which program you use?
thanks. :)
let me know via email: masaki_888@yahoo.com, thanks and success for you
please let me know via email masaki_888@yahoo.com
int latchPin = 53; //10 (SS) -> 53
int clockPin = 52; //13 (SCK) -> 52
int dataPin = 51; //11 (MOSI) -> 51
int latchPinPORTB = 0; // 53 -> PB0
int clockPinPORTB = 1; // 52 -> PB1
int dataPinPORTB = 2; // 51 -> PB2
int latchPin = 3;
int clockPin = 4;
int dataPin = 5;
I do not understand the function spi_transfer (); I do not understand how the data transmitted by the datapin
my email is jesusriosglz@gmai.com. many thanks to who can help me.
if anyone has another alternative code and send it to me I would appreciate wants. thanks
Ideally I would like to have one of these displaying time with a RTC module occasionally scrolling with news/weather/email inbox info with an ethernet module and prehaps actual temperature info from sensors. Unfortunately that is way beyond what I am capable of, coding wise. My soldering and hardware ability is good, but just learning to program.
It would be nice if the Arduing LCD library could be modified so you could control a sign matrix such as this just like a big LCD display. Do you think this would be possible?
So any ideas if I need to change the program to fit my 40x6 matrix?
Many Thanks
Can anyone Share code for 10 x 24 led matrix or explain how to modify 6 x 24 code

Anybody have the code to display the digital clock on this led matrix??
Thanks
Thanks for this great project.!!!!!
I'm using Arduino Mega 2560. do i have to change the original program???
