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.
