Good job

Super!

Thank You 😊

[@imqny3z193]

what an excellent job
Would it work with an 8x16 matrix? And what would be the changes?
Thank you ♥️

[@its015]

Yah absolutely work with 8x16 matrix.
This matrix which i made it's 8x24 matrix display.

@@its015 Can you explain to me what it means to use transistors in the output?
Will 2n2222 transistors work?

I'm using Wokwi simulator for 8x8 and now I have a problem.
I get last row light up and I don't know what cause the problem.
byte character[27][8] =

You use an NPN transistor on the row side.

[@jumbo999614]

@@its015 Can you please explain why transistor is needed. I'm a beginner.
You mean only 1 transistor? or all of the them?
Does that mean everything for row must be reversed? For row to be 0, base of transistor must be high or 1?

@@jumbo999614 Not One NPN transistor. Now 8 NPN Transistor must be used.

Excellent
Can you help me to make this
Thanks

Hello bro
Im done this matrix but the letters shows in mirrored. Why it happened. Do you have any solutions

16 x 16 can be made like this

No.
Arduino Code will be Different.
