Crowduino Uno – SD – SD Cards

There is a SD card slot on the Crowduino Uno – SD – SD Card board, with which you can easily use SD Card to record and thus to read data on the SD Card. The SD Card uses the SPI interface (D10/D11/D12) plus a CS Pin (D3 or D4) to cominicate with the main microcontroller Atmega328. First, Select the CS Pin you want to use with jumper. To make your project more flexible, you can select either the D3 or D4 pin as your CS pin for SD card. The default is D4. If your D4 have been applied for other modules, you can select the D3, but notice to modify related files in your program, which we will discuss later.
