I would like to send a sms from my arduino uno rev3 and icomsat v1.1 sim900 shield to my mobile phone. I just stack the gsm shield to the arduino without any jumper connection. Beside that, I'm also plugged in the usb cable and 9V/1.2A adapter to boot up the gsm shield. I'm using the gsm libraries provided from the official website. Below are the coding im using and the error i get. Anyone know why I get these error???
sketch_mar13a.cpp:1:20: error: SIM900.h: No such file or directory
sketch_mar13a.cpp:3:17: error: sms.h: No such file or directory
