Membuat Text Berjalan Led P10 Dengan Arduino Code Library On

The first is outdoors in blinding direct sunshine (95 degrees here this afternoon).

Or maybe that documentation will assume you also bought the driver board and power supply that were designed for it.

Maybe, just maybe, this will help: For anyone dropping into the middle of this project, Im a beginner micro hacker with an assignment to create a large scoreboard for a lively horseshoe tournament.

I need to display a total of 12 two-digit scores for 6 simultaneous games, 4 players per game.

Each of 12 players along one side of the field will have a hard-wired foot switch to increment the score for himself and his teammate.

The LED digits need to be 4 to 7 inches high, easily visible in daylight at a wide viewing angle.

I have already tried two different 7-segment displays; one was not visible at all in daylight; the other was visible only when youre standing perpendicular to it.

So, now Im going to try a 16x32 matrix that is supposedly for outdoor use.

PaulRB has been very patient, offering many helpful suggestions in the previous efforts.

Based on photos and specs, their panel appears to be very similar to what I bought.

Their Quickstart Guide (see bottom of ) indicates that you can simply connect a few data lines to Arduino and it will light up dimly.

For full-bright, I have a 300W ATX power supply that will provide 25A to the 5V power connections on the back of the panels.

Freetronics has also posted a code library on GitHub for their panels.

The Freetronics board has all its driver chips built-in and connects directly to the SPI pins (plus a few others) of the Arduino.

The problem you may have is physically connecting the panel to the Arduino - Freetronics provide an adaptor board, but you may have to rig something up with a bit of stripboard and soldering, assuming you can figure out all the necessary connections.

Looking at the schematic for the Freetronics adaptor board here, Im confused.

These are apparently shown connecting to outputs C, G and D on the Arduino - but there are no such connections Paul.

Looking at the back of the panel, we have the 16-pin connector wired up to a Nano mega328 as follows: The display lights up moderately well with power from Nano only, running on 4 AAs.

If I can get my ATX power supply to give me some voltage, I should have the display blazing soon.

The PS runs with the green wire jumped to ground, but gives no voltage on any of the cables.

Something wrong. Another mystery.

Thanks for the link to Freetronics and their DMD code library.

With the ATX power supply, they are painfully bright indoors, and fully visible outdoors in direct sunlight from a very wide angle (like 140 degrees).

Red panels are also the least expensive, as I need 12 of them.

So, still a lot of work remaining, but the hardest problem is now solved.
