{tag=LED blinker}
This example attempts to keep temperature to a fixed point by turning on a fan when a <thermistor> gets too hot.
You can test it easily if you are not in a place that is too hot by holding the <thermistor> with your finger to turn on the fan.
You can use a simple <LED> to represent the fan if you don't have one handy.
