Heute kamen meine LCDs aus Hongkong an die ich bei Ebay geschossen hatte.
Es handelt sich um die YwRobot Arduino LCM1602 IIC V1 LCDs. Da ich zur Zeit
auch ein größeres Projekt mache in dem ich eins brauche und ich PINs sparen möchte,
kam mir das Angebot ganz recht. Lange Rede kurzer Sinn, möchte nur jetzt hier schreiben
wie Ihr es anschließt um es zum laufen zu bringen.
LCD ---------> Arduino
GND ---------> GND
VCC ---------> VCC 5 V
SDA ---------> A4
SCL ---------> A5
Ihr müsst dann noch die LiquidCrystal_I2C Library in eure Arduino IDE laden.
Sketch:
/*Example Software Sketch
16 character 2 line I2C Display
Backpack Interface labelled "A0 A1 A2" at lower right.
..and
"YwRobot Arduino LCM1602 IIC V1"
Die meisten benutzen die Adresse 0x27, einige die 0x3F

Anschluesse:
GND zu GND
VCC zu 5V
SDA zu A4
SCL zu A5
