hi just looking for some advice from experienced people as im new and learning. im attempting to built a very cheap but reliable fan controller that alters the speed of the fan by temperature. am i right in thinking i can replace the resister in my diagram with a 10k Variable Resistor Pot. then this would give me precis control over configuring this device. so i can basically set the min voltage at a set temperature. say 25c = 5v ....40c = 12v so i can put the ntc in a cup of water that is 25c then i can alter the voltage using the pot to get 5v at that temperature ?
replace R2 2K2 Resister with
Type:103
Power:0.1W
Resistance:10k OHM
10K OHM Trimpot Trimmer Pot Variable Resistor 6mm
