Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

What does your code do, and what is it doing wrong?

This should help develop your code;

Thanks.. Tom.. :slight_smile:

```
const uint8_t outputPins[] = {3, 4, 5, 6, 7, 8, 9, 10};
const uint8_t inputPin = 2;

void setupcolor=#000000[/color] {
 for (const uint8_t &outputPin : outputPins)
   pinMode(outputPin, OUTPUT);
 pinMode(inputPin, INPUT);
}

void setAllOutputs(bool state) {
 for (const uint8_t &outputPin : outputPins)
   digitalWrite(outputPin, state);
}

void loopcolor=#000000[/color] {
 if (digitalReadcolor=#000000[/color] == HIGH) {
   for (uint8_t i = 0; i < 4; i++) {
     setAllOutputs(i % 2);
     delaycolor=#000000[/color];
   }
   for (int8_t i = sizeofcolor=#000000[/color] / sizeofcolor=#000000[/color]; i >= 0; i--) {
     digitalWrite(outputPins[i], LOW);
     delaycolor=#000000[/color];
   }
 } else {
   for (const uint8_t &outputPin : outputPins) {
     digitalWrite(outputPin, HIGH);
     delaycolor=#000000[/color];
