Eclectic Security

I recently bought a  Sure Electronics 8×32 LEd Matrix display and I wanted to connect it to my Arduino Duemilanove board. After a quick search on the net I found a great library written by Adam Thomas, this library comes along with clear instructions and examples how to wire and to use the display within few minutes.

Connect the display according to this schema.

| Display Label | Arduino DIO | Sure's Connector |
|      CS1      |      4      |        3         |
|       WR      |      8      |        5         |
|     DATA      |      9      |        7         |
|       RD      |     10      |        6         |
|      GND      |    gnd      |       11         |
|      +5V      |    +5V      |       12         |

Download the HT1632-AVR library and copy it in the Arduino environment.

git clone git://github.com/devdsp/HT1632-AVR.git
cp -a HT1632-AVR/libraries/* ~/arduino/libraries/
cp -a HT1632-AVR/simple8x32/ HT1632-AVR/marquee8x32/ ~/arduino/examples/7.Display/

Open the arduino sketch editor and open File > Examples > 7.Display > marquee8x32

Go into the code and change:

char *string = "Welcome to Make, Hack, Void. Have a safe and productive day.";

to

char *string = "something you like ";

Add ” delay(60); ” at the beginning of the loop in order to control the speed of the text.

Compile and upload this sketch to Arduino and enjoy.

Here you can find a video example of my first sketch.
