Microduino Read magnetic field intensity(Microduino 10dof)

Language:	English  • 中文

Objective This tutorial will teath you to use the Microduino-10DOF's HMC5883L sensor to calculate the magnetic field strength and direction, the result will be displayed in OLED. Equipment Microduino-Core Microduino-FT232R Microduino-Cube-S1 Microduino-10DOF Microduino-OLED Other equipment USB cable Schematic Microduino-OLED Microduino-Core Microduino-10DOF Microduino-FT232R Microduino-Cube-S1 Program Refer to HMC5883L10DOFOLED Debug Step 1：Stack all the upper Micrduino module, as follows: Step 2：Compile the program and download it. Step 3：Observe the OLED, use a magnet close to the sensor,the pointer will change on OLED. Result OLED will display a compass. Video http://v.youku.com/v_show/id_XNjk4NDE3MDQ4.html
