Hello everyone. I'm using a software called ArduSpreadsheet to save data from a sensor. Is it possible to save data from this software directly onto the Arduino instead of onto the computer? I also have an Arduino Wifi which might help to save over Wifi.
Depending on the Arduino you can save data to an external SD card or flash memory and read it out later. I would recommend saving in csv format for easy importing into a spread sheet or database.
Would the SD card module work with Arduino UNO r3 or Arduino UNO Wifi Rev 2?
I also noticed that the SD card module uses the 5V pin. The sensor I'm using also uses that pin. Is there a workaround for this?
Workaround for what? Is it a problem to connect a two wires to a single pin? Use a breadboard, or solder two wires one to another.
BTW, a original Uno R3 has a three 5v pins
Are you sure? The Arduino UNO R3 I'm working with only has one 5v pin slot.
And yah sorry I'm new to Arduino and didn't know you can have multiple wires soldered together to connect to one pin.
An SD module can be used with the Arduino UNO. In fact most of the signals and power are on the ICSP connector. You still need the CS signal - by default digital pin 10.
The SPI pins on the ICSP connector are in parallel with digital pins 11,12 and 13, so they can't be used for other purposes. (You could attach a second SPI device to them with a different CS pin.)
Pin IOREF is also +5V.
