Re: Power for 6 displays

Hi If you're planning to make this semi-permanent and trapping your Eleven in the project the neatest path I think would be to solder your power wires direct to the 5V and GND pads on the underside. You might also be tempted to make up a micro-USB cable that only provides the 5V and GND wires. If it...

Re: Power for 6 displays

Hi,

Re: DMD2 4x4 display

Hi Ahmed

Because I've found it unstable with ATmega328 based Arduino above 6, I've kept my designs to 6 or fewer. Others on this forum have stated they've had success with more.

Re: Death of our forum?

Crickets in reply to this. What a shame.

I'm up for a working bee to fix it up too. I'm presuming the forum has tools tools for mods to delete members and all their posts?

Really bizarre these peanuts think posting here gains them any eyeballs. Or is it only targeted because bots find it easy?

Re: Including a new font

Did you see that all the font references in this file are called that still? When you #include this font, the file name is not relevant to the compiler but the content is...these lines will mean you're defining a font called Arial_Black_16 regardless what your filename is therefore. #ifndef ARIAL_BL...

Re: life time estimation for arduino uno that derive 6 (16*32) dmds

That project was 100% running, no sleep or low power modes used.
