Arduino LCD Keypad Shield LCD1602 液晶螢幕按鍵擴展板

Arduino LCD1602 字符液晶擴展板,PCB沉金工藝加工,用料十足,主板採用全新優質2 行16 個字符液晶,不僅具有對比度調節旋鈕、背光燈選擇開關,還具4 個方向按鍵、1 個選擇按鍵和一個複位按鍵;這款1602 液晶擴展板真正意義上的將電路簡化,直接將此板插Arduino Duemilanove 控制器上即可.

擴展板模組的使用:

LCD Keypad Shield輸入輸出擴展板使用2行16個字元液晶,具有對比度調節和背光燈,使用1個類比埠口便完成5個按鍵的輸入,1個重定按鍵,未使用的IO口都擴展出來備用,充分利用IO口。佔用數字埠:PIN4(DB4),5(DB5),6(DB6),7(DB7),8(RS),9(E),10(背光控制),類比按鍵埠A0。

將LCD Keypad Shield插接到Arduino uno 控制器上,接著編譯下面的一個測試程序再下載到Arduino中,初次使用LCD Keypad Shield,先觀察LCD有沒有顯示字符,如果沒有顯示字符那可能是對比度不正確,可以使用一字起子調節RP1(順時針旋轉),調到出現清晰地字符即可。

  1. 顯示容量:16 × 2個字符
  2. 晶片工作電壓:4 . 5 — 5 . 5V
  3. 工作電流:2 . 0mA(5 . 0V)
  4. 模組最佳工作電壓:5 . 0V
  5. 字符尺寸:2 . 95 × 4 . 35(W × H)mm
