Problems with battery packs and flickering...

Post by ismaelhv » Mon Nov 09, 2015 10:38 pm

Hi, i have a Freetronics Matrix Display...with Arduino Duemilanove with DMD library.

Im using a Power Bank 10.000 mah with usb conector conected to the Panel, and 4 x AAA alkaline battery to arduino....
After 20 or 30 minutes the leds begins to flicker... during 2 or 3 minutes...It is very annoying.

When i use 4 x AAA alkaline battery with Panel and another 4 x AAA alkaline battery for arduino, dont flicker.

Any Idea about this problem??'

Thanks a lot.

ismaelhv,
Try a decent power supply for the DMD - something that will deliver a regulated 5 Volt supply with a minimum of about 2 to 3 Amps for a single DMD.
