Just to ask about the result appeared in arduino.. Is there any changes can be made towards the result obtained from arduino to any other software such as Excell? Maybe its more easy to manage the data from arduino using Excell or others. My current data are as the attachments
If you want to log your data to a file on the PC then import it into Excel:
Send the data out of the Arduino serial port in CSV format.
Use a serial monitor program like Realterm to capture the data. http://realterm.sourceforge.net/
Save the data to a file on the PC then import the file into Excel.
If you are using an older version of Excel, you can send the data direct thereto by using the PLX-DAQ macro. The advantage of this is live update of Excel graphs. You use the USB cable same as with the serial monitor.
