Thanks for replying.
I have a couple IC's on order the first POT is - IC,potentiometer,digital,100kohm,SC70-5,ISL90460TIE527Zhttp://australia.rs-online.com/web/p/products/518-431/
Basically the resister will swipe high and low with just pulsing a couple different pins.
This is how I was going to control the resistance by the speed of the pulse. (revolution of the wheel)
I'm trying to program a arduino to do this.
Before I create the circuit for the IC, im trying to get it to work first with virtual breadboard.
I can get the values to climb but not decrease. I don't know programming enough.
I want to do something similar to this
-skip to the end
But by controlling the resistance by the speed of the wheel.
My other IC Pot I might use is Digital Potentiometer 32POS 10KOhmdigital
