Project 8 lighting sequence revered

so i changes a few numbers and a few signs and i have the light going in reverse to the program in the book but the light are dim and the tilt switch has no effect now.

const int switchPin = 8; unsigned long previousTime = 0; int switchState = 0; int previousSwitchState = 0; int led = 7; long interval = 500; void setup() { for(int x = 7;x>8;x--){ pinMode(x, OUTPUT); } pinMode(switchPin, INPUT); } void loop() { unsigned long currentTime = millis(); if(currentTime - previousTime > interval) { previousTime = currentTime; digitalWrite(led, HIGH); led--; if(led == 2) { } } switchState = digitalRead(switchPin); if(switchState != previousSwitchState){ for(int x = 2; x>8;x--){ digitalWrite(x, LOW); } led = 7; previousTime = currentTime; } (previousSwitchState = switchState); }

do you think this will do anything?   for(int x = 7;x>8;x--){ or that one    for(int x = 2; x>8;x--){

what is this for?

    if(led == 2) {

and what prevents led from becoming negative? do you have a -33 pin number on your arduino?

so i changes a few numbers and a few signs

well in doing random changes you got crappy code... sorry.. you'll have to fix that...

Please correct your post above and add code tags around your code: [code][color=blue]// your code is here[/color][/code].

It should look like this:// your code is here (Also press ctrl-T (PC) or cmd-T (Mac) in the IDE before copying to indent your code properly)

Hi, Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.,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.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Also post the original code so we can see where you made the changes.

Thanks.. Tom.. :)
