کمک کمک .........!(گیرنده مادون قرمز)

با عرض سلام خدمت همگی دوستان. یک کد مربوط به ریموت مادون قرمز هست که نوشتم و هنوز نتونستم ایرادش را رفع کنم. در این برنامه قرار هست توسط یک کنترل مادون قرمز پلییر ماشین ،یک رله و دو ال ای دی را در گیرنده روشن و خاموش کنم. نمیدونم ایرادش کجاست ، لطف می کنید راهنمایی بفرمائید.

سلام دوست عزیز اگر توجه کرده باشید پروتکل سیگنال ارسالی در ریموت کنترل های مادون قرمز نصبت به کمپانی سازنده ان متفاوت است بنظرم بهتر است از برنامه های اماده داخل اینترنت که قبلا کار شده استفاده کنید بعنوان مثال برنامه خواندن ریموت sony که خودم هم کار کردم و جواب داده
