i have just started using arduino from various other C based controllers and have a uni project that im trying to sort out asap. i have 2 7segment displays mutiplexed up and working fine, but im trying to work out how i can have a potentiometer connected to control the digits that have been displayed. The hardwear works fine its just my coding abilities that i am having trouble with. In fact i have no idea how to start.
any help would be gratefully appreciated
