摘要：Progress of electronic devices, today is very rapid. Many people who utilize thetechnology has advanced now to help facilitate them in doing the job. One wayis to use a computer that currently has made great progress very rapidly. Notonly that, when this has been a lot of electronic equipment developments in themarket. We can take another example of television, air conditioner, mobilephones, and others. Based on the examples already mentioned, there is no harmif we try to make an example of such electronic devices with a more modest, butstill made a little modification. An example of a tool that can we apply a moremodest, is the Air Conditioner or as we used to call it with (AC).. The tool isFan Auto. This tool works based on the temperature that is happening around us.Because it works based on the temperature, then the device using a componentof the NTC temperature sensor and an IC Op Amp which functions as a voltagecomparator in the series. Component resistor inserted in the circuit, especiallypotentiometer very important role in this circuit whether active Atu. Because themajor obstacle, can cause this circuit becomes inactive. Liveliness of this circuitwill be indicated by the flames and turning the LED fan in the series.
