I would like to exit a particular loop if the state of an input changes from LOW to HIGH. This is the current loop:
void brakeFade() {
pixels.clear();
pixels.setBrightness(255);
pixels.fill(16711680, 0, 0);
for(int i=255; i>=10; i-=1) {
pixels.setBrightness(i);
pixels.show();
delay(5);
}
for(int j=10; j<=255; j+=1) {
pixels.setBrightness(j);
pixels.show();
delay(5);
} }
I need that loop to exit if
(digitalRead(brakeFeed) == LOW)
Changes to HIGH during the loop.
figured it out:
void brakeFade2() {
pixels.clear();
pixels.setBrightness(255);
pixels.fill(16711680, 0, 0);
for(int i=255; i>=10; i-=1) {
if (digitalRead(brakeFeed) == LOW){
pixels.setBrightness(i);
pixels.show();
delay(5);
}
else {
break;
}
}
for(int j=10; j<=255; j+=1) {
if (digitalRead(brakeFeed) == LOW){
pixels.setBrightness(j);
pixels.show();
delay(5);
}
else {
break;
}
}
}
for loop ... for(int i=255; (i>=10) or (digitalRead(brakeFeed) == LOW); i--) {
for(int i=255; (i>=10) && (digitalRead(brakeFeed) == LOW)? The OP wants the loop to continue as long as is >= 10, and the brakeFeed pin still reads as low. It should break if either of those stops being the case.
iandj, in the twoforloops ... they can both bei.... increment can be done usingi++instead ofi+=1... same with decrement
