+Cartesian coordinates for regular polygons:
+
+https://stackoverflow.com/questions/7198144/how-to-draw-a-n-sided-regular-polygon-in-cartesian-coordinates
+
+
+Let's assume you want to draw an N-sided polygon of radius r, centred at (0,0). Then the n vertices are given by:
+
+x[n] = r * cos(2*pi*n/N)
+y[n] = r * sin(2*pi*n/N)
+
+where 0 <= n < N. Note that cos and sin here are working in radians, not degrees (this is pretty common in most programming languages).
+
+If you want a different centre, then just add the coordinates of the centre point to each (x[n], y[n]). If you want a different orientation, you just need to add a constant angle. So the general form is:
+
+x[n] = r * cos(2*pi*n/N + theta) + x_centre
+y[n] = r * sin(2*pi*n/N + theta) + y_centre

+These are some potentially useful code snippets. Some may be out of date, but there you are.
+
+Mostly for Python and C++/Arduino. I'm not a very good programmer, so don't be expecting miracles here.
