So my project invovles a 16x8 LED display, using common anode RGB LEDs but only 2 colors. I want to control the display with an Arduino, which i also planned on using the 5Volt out as my source(not sure it's gonna be enough the more i get into the project??).
So i want to use a pcb because i think bread or perf board would be to bulky and too many chances for mistakes. Through research I've decided to chain 2-74HC595 registers to source the leds, and 2-ULN2803 transistor arrays controlled by 2 chained 74HC595. From my understanding i can link the clocks for each register together but need 2 seperate lines for data to each pair.
I've created a pcb through a design program and everything looks good, but not sure if its done properly, or will work when produced? Are my lines from the registers to arrays to complicated/long? Looking for opinions and suggestions.
