Microduino Design of Laptop Computer Intelligence Base
This tutorial will teach you how to control the rotation of fan with the temperature, to realize the design of a laptop computer intelligence base.
Step 1：Find out a fan, new or old one. I use the fan removed from my old laptop computer, which is a DC 5V 0.32A fan. Make some little changes to the pins, and it will be suitable to be inserted in the bread board, just like this：
Step 2：Build the circuit like this according to the schematic diagram：
This laptop computer intelligence base can control the temperature and supply power through USB too.
