I am lookiing at the use of using a digital pot as an analogue input (0 - 5v) to a pic.
As there is no apreciable load on the device I think all will be well but If anyone has knowledge of these devices and have some relevent comments I would welcome them.
Digikey.com. or most parts venders, search for digital pot. You can mark no to spi. Yes to dip etc.
