1. Is the easiest way to just run the LEDs on one board and the Servos on another?
Can I just put them in series in two groups?
2b. How do I get enough power to these 25 LEDs? Any advice?
How do get enough power to all the servos? I
Quote1. Is the easiest way to just run the LEDs on one board and the Servos on another?No, the easiest way is to use a port expander for the LEDs and just use one controller. Do the LEDs have to dim or are they just on and off?
QuoteCan I just put them in series in two groups?Normally RGB LEDs have common anodes or cathodes, therefore you can't connect these in series.
Quote2b. How do I get enough power to these 25 LEDs? Any advice?Use an external power supply with the port expander. The supply is connected to the anodes of the LEDs.
QuoteHow do get enough power to all the servos? IUse an external power supply - this will have to have a high current capacity. Measure what one servo takes, it also takes current when it is not moving.
Sorry, I meant in parallel (?), with all the anodes and cathodes in line with each other all connected to the same outs from the Arduino.
The LEDs are always on, but change colors together.
This is probably where I'm most worried.
Can I connect them in clusters to a wall wart like this one (12dcv 600mA)
12 all do the same thing and 13 do all the same thing.
