كيفية استخدام الساعة المزدوجة باستخدام DS3231 على شاشة عرض ST7735 مقاس 1.8 بوصة مع أردوينو

 

ضبط الساعة المزدوجة باستخدام DS3231 على شاشة 1.8 بوصة ST7735 يشرح هذا المشروع كيفية استخدام الساعة المزدوجة باستخدام DS3231 على شاشة عرض ST7735 مقاس 1.8 بوصة. تعرض لك هذه الساعة ساعتان: التوقيت المحلي ووقت UTC / GMT. يحتوي على 3 أزرار لـ MENU / OK ، زيادة وتقليل القيمة للساعات والدقائق واليوم في الأسبوع والسنة والشهر واليوم والفرق بين التوقيت المحلي والتوقيت العالمي المنسق (توقيت غرينتش). التخطيطي بسيط:
