Mandelbrot Arduino sketch running on Teensy 3.0 with a 3 x 0.96 inch (128 x 64 Pixel) OLED display connected via I2C. The sketch uses the Adafruit_SSD1306 library to draw on the display.

The tactile two-pin push button switch is connected to Teensy pin 2 to switch between three draw modes:

1. Refresh screen when new mandelbrot zoom is fully calculated
2. Refresh screen when one column of pixels of new mandelbrot zoom is fully calculated
3. Refresh screen whenever a single pixel of new mandelbrot zoom is fully calculated

Sketch currently zooms in fifty times.

There is no complex library used, instead real numbers simulate a complex-number operation.

The algorithm can be found on Wikipedia: Plotting algorithms for the Mandelbrot set.

A "naïve escape time algorithm" escapes when the complex part c > 2. This could be optimized.

For debugging / testing purposes an openFramework implementation can also be found under openFrameworks_mandelbrot.

It does not feature different draw modes and sleeps 200 milliseconds between zooms.

Implementation was compiled with the nightly release on 04/04/2023.
