I'm an electrician but not great with small electronics so I could use some help designing a circuit. This is what I would like to accomplish: When a thermistor temp is raised by my hand an LED slowly increases brightness. When my hand is removed the LED dims to off. I measured the thermistor. At room temp it is 10k ohms, when touching my hand it lowers to 7k. The LED has a forward V of 3-3.2V.
I believe the schematic would work but I can't figure out the appropriate resistor values. I would prefer it runs on a 9V battery but that can change
