Arduino terminal on smartphone via 1Sheeld
Turn your smart phone into a terminal and get the data from Arduino to your screen! Learn more from the examples page.
 
This shield is one of the special shields. Special shields allows your Arduino board to use some capabilities your smartphone can do, like playing music, taking a picture, getting notifications, accessing the clock data and using the touch screen for various functions. Learn more from the special shields tutorial.

Also in 1Sheeld

Terminal library simulates a serial terminal on your smartphone so that you can display any serial data on it even data of the 1Sheeld sensors shields.

Adding #define CUSTOM_SETTINGS along with #define INCLUDE_TERMINAL_SHIELD is a key that will let you unlock the Terminal shield only amongst all shields and prevent 1Sheeld library from eating your memory specially for UNO board.

Note: (println) can replace (print) in all functionalities except it inserts a new carriage and a new line after the data.
