Today, something easy : lets use a SD Card Reader with our arduino.

Can be useful for instance when you want to log datas such as temperatures or any other sensor.

I use this component from DS : SD Card Slot Socket Reader.

First the wiring : standard SPI (SCK/MOSI/MISO/CS).


Then some arduino skeches taken from the Arduino examples (note that I use CS=10 with my arduino uno, adapt if needed) :

Retrieve basic infos from your SD card and list files
Read and Write to a file (test.txt)
Dump the content from a file (test.txt)

That was it : quick and easy !

I got myself a cheap nokia 5110 lcd screen at

Lets see how easy it is to use with an arduino.

First lets get an arduino library here. (put it in your arduino libraries folder).

Then lets have a look at the wiring :

nokia 5110_bb

And now the arduino code (rename txt to ino or pde) : nokia5110_v5

And last, an ugly pic (dont look at soldering points…) :
