First time poster, new arduino user but used others through my years, opinions and suggestions appredicated:
Initially I will need to control a 4 x 10 led grid very low current LEDs using a powersupply. I will need to do any of the following and would prefer to use the mega unless shift registers are suggested otherwise:
All LEDs on at once, off at once
Dim blocks of LEDs (10, 20 at Once) while others stay on
Flash/blink all at once, many at once, or rows one at a time
Individual on/off while others remain in same state
5 inputs will be read and will determine the display pattern
I'm hoping the Mega (54 output?) can cover this because I plan to constantly change the sketch for different light displays and it seems easier to change a pin output (40 of them) than to figure out what to pass off into a shift register. Size is not a c
I'm asking in advance before I begin this project so I can program according to using shift registers or not.
