Microduino Intelligent Design of Laptop Base

Purpose This course will show you how to use temperature to control electric fan and to design an intelligent laptop base. Equipment Module Number Function Microduino-Core 1 Core board Microduino-USBTTL 1 Program download Other Equipment 5v DC fan One Bread jumper wire One box Micro USB cable One LM35 temperature sensor One Schematic Program https://github.com/Microduino/Microduino_Tutorials/blob/master/Microduino_Advanced_Tutorial/MicroduinoTempContrlFan.rar Debugging Step 1: Find a fan, such as a DC 5V 0.32A fan from the editor’s laptop. Have a little change about pins and make it suitable for breadboard. Just like this: Step 2: Build the circuit according to schematic:　　 Step 3: Download the code and compile. If there is no rotation, it means the detected temperature is below 23℃, which is the initial value of the code. You can take a hot water cup close to the temperature sensor. The higher the temperature is, the faster the fan rotates. Step 4: Make use of the principle to cool your laptop. Here we adopt a simple Bed’nTable as the support: Take the sensor and fan near and below the CPU of the laptop: Result This smart laptop base can control temperature and be powered by USB cable. Video
