Hi, You can de-linearize a pot by connecting a fixed resistor (or resistor network) from the wiper to one (or both in the case of a network) end(s) of the pot. You won't get a (truly) logarithmic curve but, depending on your requirements, you may get an acceptable curve. Hobby RC transmitters achieve their non-linear "exponential" response in this way. What are you using it for? Regards, Dave -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
