ladyada, am a final student. am working to a project that uses: arduino uno board,jpeg camera from linksprite,sim900 from seedstudio and SD card shield from ladyada.
i used pin 13,12,11,10 for the SD card as SPI,i also used pin 4,5 as uart using the newsotfserial library for the camera and the hardware uart of txo and tx1 for sim900.
the project aim is to capture image of an environment, save it to the Sd card and transmit the jpeg image through sim900 to a smartphone inform of MMS.
i need your assistance to how to do the coding, especially reading from Sd card to sim900
