Linear Pot To Log
Linear Pot To Log. Used as a volume control, this circuit still suffer from. So i found out a great tutorial on how to.
I'd just put a ruler next to the slider; Take resistance measurements from the wiper to the endpoints of the pot, call them r1 and r2. Jay98 april 3, 2015, 4:29pm #1.
Hey Guys, I Made An Adjustable Power Supply Based In An Atx Psu And A Circuit I Found On The Internet.
I actually would prefer a more. Get a resistor with a value. I'd just put a ruler next to the slider;
So I Found Out A Great Tutorial On How To.
Take resistance measurements from the wiper to the endpoints of the pot, call them r1 and r2. The x values are the linear scale values, and the y values are the logarithmic scale values. Web set the log pot at its physical midpoint.
Web I Used A 100K Resistor On A 500K Linear Pot Just As You Did.
Here is to the base 10. Get a resistor with a value. So c = 0 and k = 255 / 6.
Move The Slider In Small Even Increments;
Web adding on a 15k log faking resistor changes the loading to 100k||47k||15k||cable capacitance or about 10k||500pf. Web set the log pot at its physical midpoint. Web if it's a log, you could convert in back to linear by using the exponent.
Works Fine But There Is A Little Problem, I Only Have A Logarithmic Potentiometer Which Makes The Voltage Variation Too Abrupt.
Where k and c are constants. Web this is an application for a log pot because you are using one side of the pot to increase and decrease resistance to ground. You asked to convert linear to logarithmic, and you just plug the.
