Mandelbrot Fractal Viewer Based on Arduino

Overview

The project uses an Arduino to calculate the Mandelbrot set which can be used to get the very best image while zooming the border.

Details

From the figure, the black shape in the middle refers to the Mandelbrot set where everything that is outside the black shape is not considered to be Mandelbrot set. The first thing that needs to be done is to set the equivalence between complex numbers and pixel coordinates in order to draw the set in an image. Each pixel in the image that is drawn will have to represent a complex number and the pixel needs to be colored according to whether or not it is Mandelbrot’s.

The project uses a KS0108 GLCD where a modification will allow a byte to be written to the display and advances the cursor since it is the fastest way to write data to the screen. The code for drawing the fractal is not too difficult wherein the only change made was calculating 8 points and then drawing them to the screen as a group. This wastes less time interfacing with the LCD and matches how the screen wants to receive data.
