Draw a smiley face on your TI-84 calculator.

The TI-84 is a scientific graphing calculator manufactured by Texas Instruments. It is a versatile hand-held computer with graphic capabilities. While most of the graphical features are designed for graphing mathematical functions, there is also a free-form drawing tool. Using this tool, you can draw your own monochromatic, low-resolution pictures. With a little patience, you can draw anything you can imagine (within the technical limitations of the screen) on the TI-84. Drawing a smiley face, therefore, is a simple and straightforward procedure that allows for plenty of artistic customization.


Step 1

Press the "2nd" key and the "Draw" key at the same time. This will open the Draw menu, in which you can select from a variety of drawing modes.

Step 2

Move the cursor, using the cursor keys, down to the menu item labeled "A:Pen." Press "Enter." This activates the free-form drawing tool and opens the graph window where you can make free-form drawings.

Step 3

Move the pen cursor to about one-third of the way from the top of the screen and about one-third of the way in from the left of the screen.

Step 4

Press "Enter." This turns on the pen tool.


Step 5

Draw an eye using the cursor keys. Make a simple solid block of pixels for a simple eye. You can draw a more elaborate eye shape if you wish, with pupil, iris and eye outline.

Step 6

Press "Enter" to deactivate the pen tool.


Step 7

Move the cursor to the other side of the screen, to about one-third of the way in from the right side.

Step 8

Press "Enter" to activate the pen tool again.

Step 9

Draw the second eye the same way you drew the first.


Step 10

Press "Enter" to deactivate the pen tool.

Step 11

Move the cursor to the bottom half of the screen, to where you want to begin one end of the smile. Turn on the pen tool.

Step 12

Draw the smile using the cursor keys. Make it an upward-sweeping arc that is symmetrical. Add a second arc to create an open mouth, and add teeth if you wish to complete the smile.


Add more features if you wish to personalize your smiley face. You can add a nose, facial hair, freckles and more. You can also add eyeglasses.


Don't worry about making mistakes. You can always erase by pressing "Enter" to turn off the pen, then moving the cursor to the pixel you want to delete and pressing "Enter" again to delete the pixel.
