Hello,
i want to analogWrite from 0 - 255 and then i will stay at 255 for 0,5 hour. I try it in many ways but it dont work. I hope anybody can help me.
This is the Normal Sketch, where the PWM always continues for 30 Minuits 0 - 255 - 0 - 255 .....
////// Dimmen der LEDs
}
}
Seeing the whole program would be a big advantagePlease put it in code tags
rather than in quote tags
