Introduction: Cheapest Arduino Sd Card Module

By
About: I wasted a lot of time in my childhood because I didn't think electronics would be such an influential part of my life. However, I am not giving up yet. It is just beginning!

Description :

The SD Card Module is used for transferring data to and from a standard sd card. The pin out is directly compatible with Arduino and also can be used with other micro-controllers. It allow us to add mass storage and data logging to our project.

SD Cards work only at 3.3V and both the power and I/O levels must be accommodated. The module we are going to make uses Only resistance for level shifting and a usually 3.3V regulator for power when operating from 5.0V but in my case i am only going to use the 3.3v from the arduino board .

Step 1: Material Planning

the items needed to run this project are:

1. Arduino Uno

2. USB Cable type A to B

3. Micro Sd Card

4.SD Card Adapter

5. Resistance (3.3k *3 + 2.2k *3)

6. lm117 (optionale)

7. capacitor (1*10uf + 1*100nf) (100uf) (optionale)

8- 1n4007 Diode (optionale)

9. male pin header

10.male jumper wire

11. Breabord

12. wire

13. PCB

Step 2: Hardware Installation :

The Arduino UNO versions:

The Arduino hardware pages on the official site shows the following pin names :

*SPI:

- Pin 10 : (SS) "Slave Select"

- Pin 11 : (MOSI) "Master Out Slave In"

- Pin 12 :(MISO) "Master In Slave Out " "

- Pin 13 : (SCK) "System Clock"

Connection to SD Adapter :

10 (SS) to CS

11 (MOSI) to DI

12 (MISO) to DO

13 (SCK) to CLK

Gnd to Gnd and 3.3v or (5v option A) to vcc

After completing the connection On the Breadbord, connect the Arduino to power supply with USB cable.

Step 3: Insert Coding :

You can try an example in the Arduino Library :

Open the Arduino software

Click 'file'

Find the 'example

'Click 'SD'

Choose 'ReadInfo'

Don't forget to change the chipSelect to pin 10 ;

Step 4: Upload Source Code :

- Upload the Source code .

- And Launch the serial Monitor .

" Don't forget to Select the right Port of the Arduino board "

- The arduino should work perfectly :)

Step 5: Additional Step for Shield :

This Step is for soldering the The circuit to a pcb for more practical uses .

I position the component in this perticulaire positions for a future Instructable , You can look for more practical position of the component for more easier soldering , i found some difficulty with the pins headers to fit the arduino board , i simple advise is to position the pin headers in a way they are in complete contact withe the female pins of the arduino test the connection then put some glue with a hot glue gone .

This a inscrutable for education only .

It's more practical and safer to buy an micro sd card module with FETS built in it for level shifting and a 3.3V regulator for power when operating from 5.0V .
