這是一個基於 ESP32 的 LED 點矩陣顯示專案，整合了 WiFi 網頁設定、RTC 時間顯示、以及條碼掃描器輸入功能，適合用於創客空間或資訊看板。

這是一個基於 ESP32 的 LED 點矩陣顯示專案，整合了 WiFi 網頁設定、RTC 時間顯示、以及條碼掃描器輸入功能，適合用於創客空間或資訊看板。 本專案提供兩種顯示規格的程式碼： 1. 64x16 (寬版): 使用 16 個 MAX7219 模組 (雙排)。 2. 64x8 (窄版): 使用 8 個 MAX7219 模組 (單排)。

📶 WiFi AP 設定介面: ESP32 啟動後建立獨立熱點 (AP)，方便手機或電腦連線設定。 提供網頁介面修改三組輪播訊息及同步系統時間。 設定內容儲存於 EEPROM，斷電後資料不遺失。 ℹ️ 資訊顯示: 輪播訊息: 支援三組自訂文字訊息 (僅支援英文)，具備滾動與進場動畫效果。 時間顯示: 內建 RTC 模組，可顯示大字體時間 (時:分) 與完整日期資訊。 雙區顯示: 64x16: 分為上下兩區 (Zone Upper / Zone Lower)。 64x8: 分為左右兩區 (Zone Left / Zone Right)。 🔫 條碼掃描互動: 支援 PS2 介面的條碼掃描器。 掃描條碼後，螢幕會暫停輪播，立即顯示掃描到的內容 (停留 30 秒)。 🌱 節能排程: 內建工作時間判斷，僅在 08:30 ~ 17:30** 開啟顯示，其餘時間自動關閉以節省電力。
