RGB型分光光度計 組裝
最簡單、最容易組裝的儀器就在這了！一起動手做吧！
所需材料：
蜂鳴器：5V蜂鳴器
電路板：Arduino Uno R3 開發板
偵測器：型號 TSL-2561 傳感器
聚光透鏡：LED玻璃聚光鏡
光源：Arduino 3色LED-RGB模組 KY-016
光源選擇指示燈：3色LED模組-RGB
數值顯示器：0.96寸 藍色IIC通信小OLED顯示屏模塊

操作
1.首先插上電源即開機，按1選擇所需光源(紅R-650 nm、綠-G550nm、藍B-450nm)
2.將Cuvette置於樣品放置處，即開始量測。
第一行之L值為未換算前的穿透係數。
按下2可記錄空白組數值(螢幕顯示L0)，按3可記錄待測物數值(螢幕顯示L1)
完成量測後，連續按4兩下可直接計算獲得待測物之透光率(T)與吸收值(A)
