I keep flip-flopping on whether the pot value matters, or not, for the rate of change when used with an ADC.
Part of this project involves making a digital clock, and I want to use a pot to set the time. Since one turn is one turn and 0-255 is 0-255, it seems to me that what ever value I use will not effect how fast the number changes. I keep trying to convince myself that using a larger pot will make the numbers change slower, however. For hours, 0-12, I do not expect a problem. For minutes, 0-59, on the other hand, it seems that it might be difficult to settle on the right number if it is changing at the same rate. Or maybe that the hours would be too slow. I am getting nowhere fast listening to myself. I have almost convinced myself, now, that the only way I am going to accomplish this is to go with a multi-turn pot. Could someone please set me straight?
