大きめの青色LCDが欲しくてAliExpressで1個注文して、今日届きました。
http://ja.aliexpress.com/item/IIC-I2C-TWI-Serial-LCD-2004-20x4-Display-Shield-Blue-Backlight-for-Arduino-Free-Shipping/32599904427.html?spm=2114.13010608.0.52.jTS7Bt

Features:
A New High-Quality 4 Line 20 Character Lcd Module
Not Only Set The Contrast Control Knob Selector Switch
Also Has A Backlight And Iic Communication Interface.
For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the for Arduino Sensor Shield V5.0 sensor expansion board IIC device interface can, GM 4P sensor connection cable, programmed through the for Arduino controller, you can easily identify the slogan, sensor data records
Specification:
100% brand new and high quality
This product can simplify the circuit.
Interface: IIC/I2C
I2C Address: 0x27
Pin Definition : GND.VCC.SDA.SCL
Back lit (Blue with White char color)
Supply voltage: 5V
Pcb Size : 60mm×99mm
Contrast Adjust : Potentiometer
Backlight Adjust : Jumper
今日は動作確認をしました。
I2Cデバイスなので、電源とグランド、そして、SDAとSCL、合計4本を接続するだけ。
SDA: A4
SCL: A5
