But it just goes bananas!
It sits quiet, stationary and yellow.

4  Using Arduino / Programming Questions / Re: Converting hex expressed as string into integers on: Today at 01:37:10 pm
Code:
default:
        hex[i] = rem + '0';
        break;
Any reason for not doing a similar treatment for A-F?
A switch/case just takes up so much space.
5  Using Arduino / Programming Questions / Re: const int / int on: Today at 01:25:56 pm
I'm unclear why a discussion as to whether or  not "const"s reside in RAM has turned into a discussion about [l|r]values.
They clearly can, or simple things like Serial.print couldn't work.

it seems to me that the best approach would be to modify the Arducopter sketch to generate the output you want directly.

Awol is correct  but he forgot to add up to 40 ma with current limiting or you will kill your pin.
No, he didn't forget - that's what "up to the pin's absolute maximum current of 40mA" means - the current limit is implicit.

The pin will max out and supply possibly higher current than that for a while.
And there was me, thinking that "up to" excluded "greater than".

So, are you saying you want to process the actual motor drive PWM, or the ESC/servo drive PWM?

think its max forward current is 100ma
You could power it off an I/O pin, up to the pin's absolute maximum current of 40mA, but it wouldn't be as bright as it could be.

Define "simple".

PC supply, wall-wart, . . .
12  Using Arduino / Project Guidance / Re: Arduino multivalue problem on: Today at 09:50:54 am
Code:
settings.mode = analogRead(A0);

8 x 1.5 = 12V.
You'll need a transistor and a higher voltage supply.

Is this an R/C channel mixer problem?

Not the letter 'o', but the digit zero '0'
