Hi,
I am trying to build a circuit with a thermally controlled fan with a battery power supply. Any idea on how i should approuch this? And i have seen soom schematics with a resistor with a arrow going into it, could anyone explain what this it and how it works. I have attach a picture of the resistor thingey.
Thanks
