---------------------------------------------------------------------
شاشة TFT الملونة مقاس 1.8 بوصة ST7735 هي شاشة عرض صغيرة رائعة لاستخدامها مع مشاريع Arduino ، وهي تعمل على كل لوحة Arduino ، مثل Arduino Uno و Arduino Nano و Arduino Mega و Arduino Due.
تبلغ دقة الشاشة 160 × 128 بكسل وفي الجزء الخلفي من الوحدة يمكن للمرء أن يجد وحدة بطاقة SD! رائعة! أنا معجب حقًا بهذا العرض. سأستخدمه كثيرًا من الآن فصاعدًا!

// We are basically printing our own background. This will cause flickering, though.

// Write to the display the Variable1:
