Macro versions of pinMode and digitalWrite. Tend to be faster and smaller.
/**
* This file will reduce the size of and improve the performance of certain arduino code
* 1. It strips away about 310 bytes of overhead by replacing the implicit main function with a minimal one (which will also be faster)
* 2. It replaces the library `pinMode` and `digitalWrite` code with register-based variants - saving 120
* bytes - and which which perform faster than the built-ins for single-pin changes (for multi-pin changes,
* use the registers yourself).

vc-rev: similar to git-hash, except it works on svn repositories as well. Minimal dependency on sqlite3 for SVN repos

Fordi / how pi is calculated.md
Last active July 27, 2020 18:05
  1. Define a circle as the set of points equidistant from a center point.
  2. The Pythagorean theorem allows us to work out an equation to define the points that fit this curve, by using h as the radius
    x^2 + y^2 = h^2
  3. Setting the radius to 1 simplifies this, making our equation the unit circle
    x^2 + y^2 = 1
  4. To make this parametric (i.e., give an x, get a y), we rearrange thusly:
    y = f(x) = sqrt(1 - y^2)
  5. Since we know a circle is vertically and horizontlly symmetrical, we can simplify things by dropping the +/-, and by looking only at 0 <= x <= 1; the area under that curve will be 1/4 pi.
    ![f(0 <= x <= 1) = sqrt(1 - x^2)](http://latex.codecogs.com/png.latex?f\(0&amp;space;\\leq&amp;space;x&amp;space;\\leq&amp;space;1\)&amp;space;=&amp;space;\\
