SD card datalogger This example shows how to log data from three analog sensors to an SD card using the SD library. The circuit: * analog sensors on analog ins 0, 1, and 2 * SD card attached to SPI bus as follows: ** MOSI - pin 11 ** MISO - pin 12 ** CLK - pin 13 ** ...
Arduino模块微SD卡用户手册说明书 ARDUINO MODULE MICRO SD CARD User Manual Overview:The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). Additionally,another pin ...

Now let’s say I wanted to save my temperature data from my thermistor tutorial. I could modify the Datalogger example from the SD library to fit my need. Here it is: #include <SPI.h> #include <SD.h> double codeval; double therm_res; long series_res = 10000; double temp, temp_...
Second, the EEPROM can hold user-entered data so it doesn't get lost on restart. For example, if your program prompts the user to input various configuration settings, you could store those entries in the EEPROM. Then when the program launches again later, it can load the saved data from...
You can get fast - to save the data to a file in any FAT16 or FAT32 formatted SD card, you can read any drawing, spreadsheet or analysis program. We even have an example of how to use two free software programs to plot your data tutorials ...
One example, for a thermistor (a temperature-sensitive resistor), is: logger.thermistorB(10000,3380,10000,25,0); Where the parameters are, in order: R0: Known resistance at given known temperature (here 10,000 ohms) B: The parameter governing the curvature of the resistance-to-temperature ...
这个项目展示了如何制作一个基于Arduino的 midi 播放器。Arduino 连接到包含SD卡读卡器的 DS1307 数据记录器扩展板。Arduino 输出保存到 Data Logger Shield 中 SD 卡的 midi 文件的 midi 流。此 MIDI 流可以连接到任何可以播放音乐的 MIDI 合成器或 MIDI 设备。
