Hello everyone.
I'm in the planning phase for a project. Currently the plan is for a 32x24 LED matrix that's only going to show one image: an American flag. I'm thinking the size is going to be about the same size as a piece of paper (8.5x11) and will be 32 LEDs long and 24 LEDs tall. For the schematic, my first idea is just to have a resister with 32 LEDs in parallel going to the power supply. This design will be repeated 24 times to give me the full schematic. My first question is this: will such simple circuit work? Will I have issues with the LEDs on the far end not lighting up completely/at all, and if so then how can I correct for this? My second questions concerns the current draw; I'll be using 768 LEDs for this if it's going to be 32x24, and with each LED taking about 20ma, that'll be 15.26A. I know there's a lot of LEDs, but 16A seems like too much current for a bunch of LEDs to draw. Is there something fundamental about current draw that I'm not understanding that will cause the draw to be less severe, or will I really need a 16A power supply?
And help or advice will be appreciated, thanks!
