this is program that works for AC dimmer:
CODE
// Testing sketch for 50Hz !!!

#include <TimerOne.h>

unsigned char channel_3 = 6; // Output to Opto Triac pin, channel 3
unsigned char CH3;
unsigned char i=0;
unsigned int delay_time=2500; // delay ms or SPEED
unsigned char clock_tick; // variable for Timer1


void setup() {

pinMode(channel_3, OUTPUT);// Set AC Load pin as output
attachInterrupt(1, zero_crosss_int, RISING);
Timer1.initialize(100); // set a timer of length 100 microseconds for 50Hz or 83 microseconds for 60Hz;
Timer1.attachInterrupt( timerIsr ); // attach the service routine here

}

void timerIsr()
{
clock_tick++;

if (CH3==clock_tick)
{
digitalWrite(channel_3, HIGH); // triac firing
delayMicroseconds(10); // triac On propogation delay (for 60Hz use 8.33)
digitalWrite(channel_3, LOW); // triac Off
}
}



void zero_crosss_int() // function to be fired at the zero crossing to dim the light
{
// Every zerocrossing interrupt: For 50Hz (1/2 Cycle) => 10ms; For 60Hz (1/2 Cycle) => 8.33ms
// 10ms=10000us , 8.33ms=8330us

clock_tick=0;
}



void loop() {
CH3=95;
delay(delay_time);

CH3=90;
delay(delay_time);

CH3=85;
delay(delay_time);

CH3=80;
delay(delay_time);

CH3=75;
delay(delay_time);

}

I would like to fuse them in one program,i don't need lcd or dht11,i just need to control my ac dimmer with slider,thanks in advance

If anybody can use this as help feel free to try my code at least to start your project.
Arduino Yun code:

unsigned int clock_tick; // variable for Timer1
int pin12 = 12;
int dac = 0;
int DigitalPin[] = {2, 12, 13};
int DacPin = 3;
YunServer server;
void setup() {
pinMode(channel_3, OUTPUT);// Set AC Load pin as output
attachInterrupt(1, zero_crosss_int, RISING);
