I2C (I-square-C i.e IIC) means inter-integrated communication protocol. Anleitung zum LCD Display mit I2C Anschluss Mit einem LCD-Display kann man Buchstaben und Ziffern darstellen. Posted on September 19, 2019 May 2, 2020 by Blogthor. You can plug-in this module directly to the pins of the regular LCD and using I2C communication with Arduino (or any microcontroller) you can transmit the data. Learn to use and operate an I2C LCD with Arduino using the LiquidCrystal_I2C library. I2C LCD DISPLAY VERSION 2: Marked "Arduino-IIC-LCD GY-LCD-V1" NOTE: The wire connections are in a different order! Microcontroller Arduino. Find this and other Arduino tutorials on ArduinoGetStarted.com. I2C LCD Adapter At the heart of the adapter is an 8-Bit I/O Expander chip – PCF8574. При использовании LCD I2C модуля с дисплеем 20х04 ничего в коде изменять не требуется, cледует только задать правильную размерность */ Author: Frank de Brabander. We have seen how the I2C bus works, and how we can create our own I2C sensorsand devices using an Arduino. VCC of the i2c module to 5V pin and connect the GND as well. Suggest corrections and new documentation via GitHub. LiquidCrystal I2C. Connecting the I2C LCD to Arduino. Kenapa I2C ?
