In our earlier tutorial, Writing to an SD Card<\/strong><\/a>, we learned to write to an SD card. As you might have experienced, in order to see what\u2019s been written, we need to pop out the SD then connect it to a computer, which obviously is not very convenient all the time. So, in this tutorial we will read a text file (same file\/information that we wrote in previous tutorial<\/a>) and send that text to a computer. Our communication between Netduino SD card and Computer is established via Serial Communication using USB to UART-TTL device. So, the information will be transferred to a computer in a Component Object Model (COM) port.<\/p>\n

There are two major parts of this tutorial; first reading the data from SD Card and sending it to a computer, second an application listening to a COM port to retrieve the data. Besides these, in this tutorial we will touch on following major objects:<\/p>\n
