Touch Pad

The T Watch has a reliable input output using the touchpad module. We have seen how to print to the touch screen in the Hello World example. In this section we will get user input (touches) and display output using the touch pad.

Serial Input/Output

For debugging purposes the Serial Port will be very useful. We have already used the serial port to write to the T-watch's program memory (when we loaded compiled binary of helloWorld.ino). In this section we will learn to programmatically read and write to the Serial Port.
