Microduino Design of Laptop Computer Intelligence Base

Objective 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. Equipment Module Number Function Microduino-Core 1 Core board Microduino-USBTTL 1 Program download Other equipment 5v DC fan 1 Bread board jumper 1 box micro USB cable 1 LM35 temperature sensor 1 Schematic Diagram Program https://github.com/Microduino/Microduino_Tutorials/blob/master/Microduino_Advanced_Tutorial/MicroduinoTempContrlFan.rar Debugging 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： Step 3：Download the code and compile and run it. At this time if the fan doesn’t rotate, the temperature it detects is lower than 23 degrees, which is the initial value. You can exhale toward the temperature sensor, and the fan may rotate. The higher the temperature, the faster the speed of rotation. Step 4：Find a way to use it to cool down your laptop computer, and use a simple bed table to support it： Make the sensor and the fan as close as you can to the bottom of your computer around the CPU： Result This laptop computer intelligence base can control the temperature and supply power through USB too.
