With this you just type the text you want on your computer and your 5x5 dot matrix shows the message.
~5x 100ohm resistor
~and a bit of skripting
It took me a while to figure this all out but in the end it was quite rewarding. not really practical though. :)
Plz comment and let me know what you think.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: You Wil Need..
Arduino- have the uno-
Sharp nose [liers for hard to reach places (optional)
5x100 ohm resistors (brown black brown)
Step 2: Diagram
I know it looks sideways but this is how i connect it to my Arduino
Step 3: Starting With Connections
Here is how i coneckted the leds. it gets a bit conplecated but works. feel fre 2 try own metheds
I made it that all the anodes are connected down, like in the pic. the cathodes are so that only 2 are connected. The one on the left shears a line with the one on his right.
The catrodes are then connected to allow a horizontal connection as n the photo.
I just wired them all to a neutral location so that can connect them to my arduino easier
Step 5: To Arduino
now just connect according to the diagram with the resistors on the cathrodes.
Step 6: Now Connect to Pc
