Hi.
With the help of members in the forum, in 2013, a novice like me I completed a fully functioning scoreboard with home score, away score, timer, clock, and temp display. I made each of the 15 large digits (common anode) from 330 LEDs - that was alot of soldering!!!. Each segment draws either 105mA max or 120mA (depending on which segment it is).
I was toying back there to eventually run this via microcontrollers instead of discrete components. In my thread called "count down timer for my soccer club", someone on the forum called "MMcLaren" suggested the use of 4 x MIC5891, however I can't contact him to chase this further (see part picture below of an image he sent me):
However, since then I've been told that I can use 15 x TPIC6B595N shift registers. I'm told these can drive 150mA each pin, so I think this might be the best solution. I also think they don't need any external mosfets, etc. I want to drive this via code written in Arduino. Can I please get some feedback as to whether this is a good way to go. Thanks in advance.
