hi there
i have tried to make a code for my arduino what has 4 LED's the first one turns on waits 15mins turns back off and a delay for 1 second and so on then returns to the start. but seem to be getting error messages when uploading i am still a newbe to this so i expect someone will look at this and laugh and tell me i did a stupid mistake. 

any help will be grateful thanks

Code:

// Example 01: Lighting Timer

#define A_light 13 // Light A on pin 13
#define B_light 12 // Light B on pin 12
#define C_light 11 // Light C on pin 11
#define D_light 10 // Light D on pin 10


void setup() {
  pinMode(A_light, output)
  pinMode(B_light, output) //seting the digital
  pinMode(C_light, output) //pin's as output
  pinMode(D_light, output)
}

void loop ()
{
  digitalwrite(A light, HIGH); //turn A light on
  delay(900000); // wait for 15 mins
  digitalwrite(A light, LOW); // turn A light off
  delay(1000);  // turn all off for 1 second
  digitalwrite(B light, HIGH); //turn B light on
  delay(900000); //waint for 15mins
  digitalwrite(B light, LOW); //turn B ligt off
  delay(1000); // turn all off for 1 second
  digitalwrite(C light, HIGH); // turn C light on
  delay(900000); // turn all off for 1 second
  digitalwrite(C light, LOW); // turn C light off
  delay(1000); //turn all off for 1 second
  digitalwrite(D light, HIGH); // turn D light on
  delay(900000); // D light off
  digitalwrite(D light, LOW); // turn D light off
  digital(1000); //turn all off for 1 second
 
}

That code won't compile, so can't possibly run.

"output" is not the same as "OUTPUT".
"digitalwrite" is not the same as "digitalWrite".
"A light" is not the same as "A_light"
Needs more semicolons.

Simplify, try smaller sketches, experiment until you get code to compile, then try to run it.

To save time when it comes to debugging, compress time:

Code:

#ifdef DEBUG
#define LONG_DELAY (15UL * 60UL * 1000UL)
#define SHORT_DELAY (1000UL)
#else

#define LONG_DELAY (15UL * 60UL * 10UL)
#define SHORT_DELAY (100UL)

#endif

now i have got it wrapped around my hedad now and all confused lol

[Reply #3 on:]

I don't know what that means.

[Reply #4 on:]

confused dont no how to sort this out

[Reply #5 on:]

Use the compiler and my comments above to help you make corrections.

This compiles.

Code:

#define A_light 13 // Light A on pin 13
void setup()
{
  pinMode(A_light, OUTPUT);
}

void loop ()
{
  digitalWrite(A_light, HIGH); //turn A light on
  delay(900000UL); // wait for 15 mins
  digitalWrite(A_light, LOW); // turn A light off
  delay(1000UL);  // turn all off for 1 second
}

hi there i got it working thanks for the help i only scanned over what you said in the first place after slowing down a bit i saw what you were getting at

this is the current code

Code:

// Example 01: Lighting Timer

#define A_light 13 // Light A on pin 13
#define B_light 12 // Light B on pin 12
#define C_light 11 // Light C on pin 11
#define D_light 10 // Light D on pin 10


void setup() {
  pinMode(A_light, OUTPUT);
  pinMode(B_light, OUTPUT); //Setting the digital
  pinMode(C_light, OUTPUT); // pin's as output
  pinMode(D_light, OUTPUT);
}

void loop ()
{
  digitalWrite(A_light, HIGH); //turn A light on
  delay(900000); // wait for 15 mins
  digitalWrite(A_light, LOW); // turn A light off
  delay(1000);  // turn all off for 1 second
  digitalWrite(B_light, HIGH); //turn B light on
  delay(900000); //waint for 15mins
  digitalWrite(B_light, LOW); //turn B ligt off
  delay(1000); // turn all off for 1 second
  digitalWrite(C_light, HIGH); // turn C light on
  delay(900000); // turn all off for 1 second
  digitalWrite(C_light, LOW); // turn C light off
  delay(1000); //turn all off for 1 second
  digitalWrite(D_light, HIGH); // turn D light on
  delay(900000); // D light off
  digitalWrite(D_light, LOW); // turn D light off
  delay(1000); //turn all off for 1 second
 
}

but now i would like to add a switch to alter the 15minute delay time so when buttons not pushed there will be a 15 minute delay between them all and when the button is pressed there will be a 30 min gap between them all i have started to adjust code as far as i am able to any help would be appreciated

Code:

// Example 01: Lighting Timer

#define A_light 13 // Light A on pin 13
#define B_light 12 // Light B on pin 12
#define C_light 11 // Light C on pin 11
#define D_light 10 // Light D on pin 10
#define button 7  //   Button on pin 7


void setup() {
  pinMode(A_light, OUTPUT);
  pinMode(B_light, OUTPUT); //Setting the digital
  pinMode(C_light, OUTPUT); // pin's as output
  pinMode(D_light, OUTPUT);
  pinMode(button, INPUT);  //setting as an input
}

void loop ()
{
  digitalWrite(A_light, HIGH); //turn A light on
  delay(900000); // wait for 15 mins
  digitalWrite(A_light, LOW); // turn A light off
  delay(1000);  // turn all off for 1 second
  digitalWrite(B_light, HIGH); //turn B light on
  delay(900000); //waint for 15mins
  digitalWrite(B_light, LOW); //turn B ligt off
  delay(1000); // turn all off for 1 second
  digitalWrite(C_light, HIGH); // turn C light on
  delay(900000); // turn all off for 1 second
  digitalWrite(C_light, LOW); // turn C light off
  delay(1000); //turn all off for 1 second
  digitalWrite(D_light, HIGH); // turn D light on
  delay(900000); // D light off
  digitalWrite(D_light, LOW); // turn D light off
  delay(1000); //turn all off for 1 second
 
}

You're going to have to change the constants in the delays for variables.
Watch out for 'int' arithmetic overflowing/wrapping with such large numbers.

i know this will not work but am i barking up the right tree

Code:

void loop ()
{
  val = digitalRead(button); //read input value and store it
 
  digitalWrite(A_light, HIGH); //turn A light on
  delay(900000); // wait for 15 mins
  if (val == HIGH) {
    delay(900000); // delay for 30 mins if button is HIGH
  }
  { 
  digitalWrite(A_light, LOW); // turn A light off
  delay(1000);  // turn all off for 1 second
  digitalWrite(B_light, HIGH); //turn B light on
  delay(900000); //waint for 15mins
  digitalWrite(B_light, LOW); //turn B ligt off
  delay(1000); // turn all off for 1 second
  digitalWrite(C_light, HIGH); // turn C light on
  delay(900000); // turn all off for 1 second
  digitalWrite(C_light, LOW); // turn C light off
  delay(1000); //turn all off for 1 second
  digitalWrite(D_light, HIGH); // turn D light on
  delay(900000); // D light off
  digitalWrite(D_light, LOW); // turn D light off
  delay(1000); //turn all off for 1 second
 
}

Except for the incorrect number of {, yes, you are barking up the right tree.

Now, knock it off. The barking is annoying.

[Reply #10 on:]

i have stopped barking now 
i have played with it a few times now and still cant get this to work sorry if im being a little bit thick.

thanks Joe

First implement Awol's advice: replace all 900000 with 900000UL The compiler will try to interpret it as a 16 bit integer constant otherwise, which won't fit and will give you odd results.

Then - what isn't working?

Also, for the test phase, you might consider using 90000UL instead - it's still large enough to need the UL, but you can run through the program without dying of boredom.

hi got it all working now thanks all for your help 

[Reply #13 on:]

hi there again
i have made a few adjustments and added an extra 4 switches to turn off any one of the 4 lights but letting the sequence carry on i can upload this code to my controller but i cant seem to get any of the four switches to work dont know if any one notices any faults in this if so please tell me
thanks

The semicolons on the if statements can't be helping
