5X5 dot matrix on Arduino

With this you just type the text you want on your computer and your 5×5 dot matrix shows the message.

Used:
~25 leds
~Arduino uno
~5x 100ohm resistor
~and a bit of skripting
5X5 dot matrix on Arduino
It took me a while to figure this all out but in the end it was quite rewarding. not really practical though. 🙂
Enjoy.

Plz comment and let me know what you think.

Step 1: You wil need..

25 leds
Breadboard
Arduino-  have the uno-
Sharp nose [liers for hard to reach places (optional)
5×100 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.

Step 4:

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.
