Screens

Using screens

With an Arduino Display Shield

The display shield contains a resistor keyboard.

To include a Keyboard handler block under 'Miscellaneous' to let BrainBuilder manage the key handling for you. This makes using screens easier. If you want to handle the keys yourself, do not include a keyboard handler.
