Led fading using Array function

[hadi-mir]

Hey Mates,
I wanted to simulate the Dawn light with my arduino Uno using array implementation.
I desired to change the brightness of the LEDs using fade effect( Smoothly and keep it unchanged until the next function called out) from 0 brightness to specific values in array ( it means specific brightness for each LED).
I wrote my code and compiled it but unfortunately nothing happens when I upload it to my device.
The device is already connected and I have tested some other on/off led codes.
Here is my pre-code:

//Dawn Light Simulation
int LEDArray[] = {3, 5, 6, 9, 10, 11};
int LedNum = 6;
int i;
int j;

int Dawn[] = {30, 20, 20, 20, 100, 0};

int Current[] = {0, 0, 0, 0, 0, 0};
unsigned long time_for_fadestep;
#define Fade_Interval 1200;

void setup() {

for (int i = 0; i < LedNum; i++)
pinMode(LEDArray[i], OUTPUT);

}

void DawnMode()
{
if (millis() > time_for_fadestep) {
time_for_fadestep = millis() + Fade_Interval;
for (int j = 0; j < LedNum; j++){
if (Dawn[j] > Current[j]) Current[j++];
if (Dawn[j] < Current[j]) Current[j--];
analogWrite(LEDArray[j], Current[j]);

}

}
}
void loop() {
DawnMode();
delay(5000);
}

Hello, and many appreciate for you note, I will do it certainly

for (int j = 0; j < LedNum; j++){
if (Dawn[j] > Current[j]) Current[j++];
if (Dawn[j] < Current[j]) Current[j--];

Why are you messing about with the for loop index inside the for loop?
It looks like a crazy thing to do.
What are you trying to achieve?

The current array always seems to have zero in it and it never changes.

I will do it certainly

Please also run auto-format on your code using ctrl-T in the IDE editor, to properly highlight the code blocks.

Hello Mike,
The reason of using For() is to comparing each index's value and change the value in the Current[j] array.
If I remove For() , it just compare the values and does not increment or decrement the values. it's working now,
with some updates I could make the transition between values smoothly.

For the sake of others who might come across this thread in the future can you post your finished code please.

@Grumpy_Mike

can you post your finished code please.

Having read the forum instructions for posting code and everything else.

I'm making some updates, and found some bugs as well, I will share it tomorrow
