I dont really understand exactly how digital potentiometers work so ill just explain what im trying to do. I am going to be using either a pic axe 18m2 or 20x2 i havent deciceded but it will have an infrared reciever and a remote that i would like to use to adjust the resistance of the potentiometer. when i press one button it will raise the resistance by whatever increment then when i press another it will lower it. is it possible to just have the potentiometer hooked to 2 pins of the microcontroller. one to increase and one to decrease and whenever i press the button to increase the resistance, curreent gets sent through that lead to the pot and thru the other lead to decrease. the resistance i am wanting to change is in a whole other circuit. it is an rc servo so when resistance is increased less volts will go to the servo and it will be less "touchy". is what i am trying to do possible?
