Hi!
I have to make a simple circuit with UA741 OPAMP, NTC and a potentiometer for temperature monitoring.
I have an 2K2 NTC which would be connected to one gate and I have to put some potentiometer to the
other gate of the UA741.
With the potentiometer I should adjust the temp between 30-60C or something around.
So, here I need some help.
What value of the potentiometer should I use to have a larger step of temperature adjustment.
I mean, I won't does If I move the potentiometer 1mm left or right does the temp moves 30C etc.
I played around with several potentiometer but it went over my head and I have no usable info also...
![Sad :(](https://www.eevblog.com/forum/Smileys/default/sad.gif)
Any advice which value should I use of the potentiometer to have a nice path in temperature until I move the potmeter
would be great for me.
Thanks for any advice.
My best regards.
