यहां तक कि eBay की वेबसाइट पर यह उल्लेख किया गया है कि मैं Arduino Mega के अटैचमेंट पर 2.4 "TFT LCD शील्ड डिस्प्ले का उपयोग नहीं कर सकता। समस्या यह है कि मैंने गलती से यह शील्ड खरीदी है। मैं इस शील्ड को Arduino Mega 2560 पर रखना चाहता हूं। क्या यह है। मेगा और 2.4 को मिलाने का तरीका "डिस्प्ले शील्ड?
नोट: मैंने अपने दोस्त के Arduino Uno पर कोशिश की। शील्ड बहुत अच्छा काम कर रही है।
नोट: नीचे दिया गया फोटो मेरे प्रश्न का निर्धारण कर रहा है। प्रदर्शन मेरे Arduino के कोड को नहीं चलाता है। यह केवल अपनी एलईडी चलाता है।
