This example program works like an Etch-a-Sketch. As you rotate the two motors, a continuous line is drawn on the NXT screen. Lines that go off the screen will reappear on the opposite side of the screen. For instance, if your line goes off the right side of the screen it will reenter on the left side of the screen.

  This program converts polar coordinates into Cartesian coordinates.

This example takes input from the motors and uses it to move a circle around the NXT screen.

This example allows the user to play a game on the NXT screen. The user is the circle on the left side of the screen. When the orange button is pressed, the circle moves up, otherwise it moves down. The object of the game is to avoid the the flying rectangle, the ceiling, and the floor.

This program uses the display text icon to display "Hello World" in line four.

This example allows you to move a point around the NXT screen. The point's previous positions are also displayed on the screen. You can use this program to make point-by-point drawings.

This example draws a sine and cosine wave on the NXT screen.

This example draws a series of straight lines to produce curved geometric shapes on the NXT screen.

This example demonstrates basic NXT screen control, it displays a circle on th e NXT screen for two seconds, erases it, and then displays a rectangle for two seconds.

This example uses a random number generator to plot the Sierpinski triangle fractal on the screen of the NXT brick.
