I want to make a variable resistor, whose resistance will change with time like a sine curve... is it possible? is there any 'not too complex' ckt for that as I am a beginner? pls help.
although a lot of applications can do it digitally, more easily and more accurately.
You could make a digital potentiometer change with time, by using a microcontroller to drive it. However, if you are using a microcontroller, it is just about as easy to do the whole thing digitally.
