fade 12 led please help

[arty_artist]

I want to fade 12 led like a link youtube at Below
BUT in pin 1-2-4-7-8-12 a light of led not fade
I use arduino uno 6 pwm
How i will fix the code Please...HELP ME

[system]

You're trying to do PWM on pins that don't have hardware PWM.

You can't do that.

Time for a rethink. (Software PWM isn't that hard to do)

(Your code is also too long)

It is also not posted correctly, please read the rules.

arty_artist,

Not all of the pins on the Arduino can be used for Pulse Width Modulation, which allows you to fade the LEDs.

The Arduino Uno has only 6 pins that you can use for fading LEDs. They are pins 3, 5, 6, 9, 10 and 11. If you have LEDs connected to any other pin, you can't use those pins for fading the LEDs, only pins 3, 5, 6, 9, 10 and 11.

So, your LEDs connected to pins 1, 2, 4, 7, 8 and 12 will not fade.

I haven't watched the YouTube video who's link you posted, but I have a feeling he was using an Arduino Mega, which has many more PWM pins available than your Uno does.

Hope this helps.
