Hi, I'm new to arduino and I want to build a custom gauge cluster for a car over the next few months. It will have about 30 7-segment LED displays (30 digits), 2 bar-graphs, about 10 1-led indicators, and will read input from about 10 sensors. The LEDs, displays and bar-graphs will be controlled by few MAX7219 chips.
So my question is, will Arduino Mega be enough for it? What other alternative boards can I use for this?
