hi
i'm trying program arduino control relay tft screen
so there 2 colors on tft screen half red(relay off) , other half green(relay on) want press green light turn relay , red light turn off relay.

utft myglcd(ili9327,38,39,40,41);   // remember change model parameter suit display module!
utouch  mytouch( 6, 5, 4, 3, 2);

int x, y;

void setup()

  mytouch.inittouch();
  mytouch.inittouch(landscape);
  mytouch.setprecision(prec_medium);

}
void onoffbutton()

}
void loop()

if (mytouch.dataavailable()){
  mytouch.read();
  x=mytouch.getx();
  y=mytouch.gety();
  if ((x>=0) && (x<=240) && (y>=0) && (y<=240));

 digitalwrite(relay,0);

}



  // off button
 if (mytouch.dataavailable()){
  mytouch.read();
  x=mytouch.getx();
  y=mytouch.gety();


 digitalwrite(relay,1);

 }

}







you not testing right conditions in area.

code: [select]



  // off button
 if (mytouch.dataavailable()){
  mytouch.read();
  x=mytouch.getx();
  y=mytouch.gety();


 digitalwrite(relay,1);



you need test region of screen touched off condition.

add
code: [select]

if ((x>=240) && (x<=390) && (y>=0)&& (y<=240));

before

code: [select]

 digitalwrite(relay,1);
