Are you making the "with button" or "without button" version?
I think interruptibleDelay() is a clever way to run blocking code without missing a button press.
Using the "with button" LED configuration in Post #8, it seems this should be the "layers" (top, down)
const int layer1[] = {8, 2};
const int layer2[] = {7, 9, 3};
const int layer3[] = {6, 4};
const int layer4[] = {5};
or this (bottom, up)
const int layer1[] = {5};
const int layer2[] = {6, 4};
const int layer3[] = {7, 9, 3};
const int layer4[] = {8, 2};
I like "random" animations...
void runRandom() {
int r = random(8); // eight LEDs
digitalWrite(pins[r], HIGH);
interruptibleDelay(ANIMATION_DELAY);
digitalWrite(pins[r], LOW);
if (checkButtonPressed()) {
advanceMode();
}
}
