I am facing difficult to connecting my microSD card module with my Arduino uno ,I tried many codes and tried all the ports on uno.
The pins on my SD card module are:-
1--->CS
2--->SCK
3--->MOSI
4--->MOSO
5--->VCC
6--->GND
Which module?
Which library?
How big is the card?
Please draw the wiring; an Uno does not have a CS pin (trying to understand your description of connections).
Topic moved to a more suitable category on the forum.
The SD library by Arduino.
The storage of memory card is 4gb is formatted to fat32.
MicroSD card module, I don't know the origin.
The above pin are on my microSD card module. I apologise of the incomplete statement
In that case don't use it. MicroSD cards are 3.3V devices and you can not directly connect them to an Arduino Uno without the risk of damaging the card. So if you don't know what you have, you're taking a risk.
The wiring should be
| SD module | Uno |
|---|---|
| CS | SS (10) 1 |
| MOSI | MOSI (11) |
| MISO | MISO (12) |
| SCK | SCK (13) |
| GND | GND |
| Vcc | 3.3V 2 |
- CS can be connected to any pin; you specify that in the begin method of the library.
- If (!!) the module has level converters and a 3.3V regulator, Vcc of the module should be connected to the Uno's 5V and it's safe to use it with the Uno. So it is important to know what you have.
Thank you
