I want an input pot to change the timing for lighting a sequential LED array, original post on that is here: http://www.picaxeforum.co.uk/showthread.php?t=7752
The supply voltage for the LED arrays is 9V, then I would use a 5V reg off the 9V to feed the picaxe.
I was thinking I would just use 2 10k resistors, one of them variable from the 9V source for the ADC input, so it would be ~0V-4.5V. This sound like a keen plan or should I be doing this a different way for some reason? Would 100k and 100k be better? I'm pretty new with electronics still, just want to put this together the best way possible.
Thanks for the help!
