夏天到了想要開啟冷氣才發現遙控器螢幕黑屏了，本想丟掉換新的，後來google一下，發現黑屏是可以救的，於是死馬當活馬醫，反正壞了也沒關係～～
首先把遙控器拆開，LCD的背板已經黑黑的，粉紅色的是導電膠條，要對應基板金手指不要弄掉了～
用美工刀尖端把背膠撕開，注意平均施力避免玻璃破裂
撕掉後看起來就是一塊透明玻璃(背膠太黏，黑線都掉漆了....)
找銀龍貼紙(背膠面是銀色的可以反光)，裁切適合大小貼合在LCD玻璃上
注意表面清潔，避免異物及氣泡
完成～～(技術不好表面還是有氣泡 >_<)
把LCD跟基板組合好，注意導電膠跟金手指的位置，上電測試，可以正常顯示，已經沒有黑屏了～～
忽然間有個大膽的想法，遙控器基板按鍵的兩端都有獨立的pad，那是否可另外拉線來控制遙控器呢？
第一個我就想到用Siri來控制遙控器開啟/關閉冷氣，還可以調溫度，因此只要控制3個按鈕，因此要設計一個HomeKit裝置控制3個Switch
之前有設計一個ESP8266 HomeKit裝置，3個GPIO 控制3個光偶，模擬開關可以控制鐵捲門遙控器，就直接拿來套用
線路圖
ESP8266 HomeKit 程式庫選用這個，目前使用上比較穩定 Arduino-HomeKit-ESP8266
可以用這個範例2去修改
範例只有一個Switch，因此要再增加兩個，程式修改如下，請參考
wifi_info.h 可以刪除，我已經修改為WiFiManager，不用每次修改WiFi密碼

* HAP section 8.38 Switch
* An accessory contains a switch.
*
* This example shows how to:
* 1. define a switch accessory and its characteristics (in my_accessory.c).
* 2. get the switch-event sent from iOS Home APP.
* 3. report the switch value to HomeKit.
*
* You should:
* 1. read and use the Example01_TemperatureSensor with detailed comments
* to know the basic concept and usage of this library before other examples。
* 2. erase the full flash or call homekit_storage_reset() in setup()
* to remove the previous HomeKit pairing storage and
* enable the pairing with the new accessory of this new HomeKit example.

燒錄好程式就可以測試配對，配對代碼 111-11-111 (8個1)
配對好就會顯示在"家庭"裡面
接下來就是DIY時間了，因為遙控器種類太多，所以依現況改造
把相對應按鍵的Pad 焊上漆包線(選擇較細軟的訊號線，避免影響實體按鍵操作)
用紙膠帶固定漆包線避免干擾按鍵，一共4條訊號線，對應按鍵：
ON/OFF : 對應Pin 1- 2
升溫 : 對應Pin 2- 4
降溫 : 對應Pin 3- 4
確認完成後把訊號線拉到背面，就可以先將按鍵組裝起來
將訊號線跟ESP8266 裝置組裝起來，遙控器電源一般為3V，所以可以直接使用ESP的電源即可
組裝完成，上電測試一下，顯示功能正常
接下來看看測試的影片～～
