/**************************** START TRANSITION FADER *****************************************/ | |
// From https://www.arduino.cc/en/Tutorial/ColorCrossfader | |
/* BELOW THIS LINE IS THE MATH -- YOU SHOULDN'T NEED TO CHANGE THIS FOR THE BASICS | |
The program works like this: | |
Imagine a crossfade that moves the red LED from 0-10, | |
the green from 0-5, and the blue from 10 to 7, in | |
ten steps. | |
We'd want to count the 10 steps and increase or | |
decrease color values in evenly stepped increments. | |
Imagine a + indicates raising a value by 1, and a - | |
equals lowering it. Our 10 step fade would look like: | |
1 2 3 4 5 6 7 8 9 10 | |
R + + + + + + + + + + | |
G + + + + + | |
B - - - | |
The red rises from 0 to 10 in ten steps, the green from | |
0-5 in 5 steps, and the blue falls from 10 to 7 in three steps. | |
In the real program, the color percentages are converted to | |
0-255 values, and there are 1020 steps (255*4). | |
To figure out how big a step there should be between one up- or | |
down-tick of one of the LED values, we call calculateStep(), | |
which calculates the absolute gap between the start and end values, | |
and then divides that gap by 1020 to determine the size of the step | |
between adjustments in the value. | |
*/ | |
int calculateStep(int prevValue, int endValue) { | |
int step = endValue - prevValue; // What's the overall gap? | |
if (step) { // If its non-zero, | |
step = 1020 / step; // divide by 1020 | |
} | |
return step; | |
} | |
/* The next function is calculateVal. When the loop value, i, | |
reaches the step size appropriate for one of the | |
colors, it increases or decreases the value of that color by 1. | |
(R, G, and B are each calculated separately.) | |
*/ | |

val += 1; | |
} | |
