Improved Arduino Robot Face on Parallel TFT LCD

Improved the Arduino Robot Face by putting it on a 2.4 inch Parallel LCD. The LCD is a HY-TFT240 to be exact. This larger 320 by 240 LCD gives more room for adding a mouth as well as bigger eyes. However the LCD requires 8 data bits, 4 control lines power and ground. So there are more wires required. You can even get this type of LCD in a shield that plugs right into the Arduino. That arrangement will not fit in the robots head.

Here are two of the many possible faces.

This is what the setup looks like when it is not installed in the robot.

This is the video of the robot faces.

This is the code. I do not have an interface to select what face to display yet.
