How do you connect 16×2 LCD to ESP32?

How do you connect 16×2 LCD to ESP32?

Circuit diagram

1. connect pin 1-16 of I2C module to pin 1-16 of LCD display.
2. SDA pin of I2C module -> SDA pin of ESP32 i.e D21.
3. SCL pin of I2C module -> SCL pin of ESP32 i.e D22.

How do you use I2C LCD with ESP32?

Getting the LCD Address With the LCD properly wired to the ESP32, upload the following I2C Scanner sketch. After uploading the code, open the Serial Monitor at a baud rate of 115200. Press the ESP32 EN button. The I2C address should be displayed in the Serial Monitor.

What is LCD I2C?

I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features.

Does ESP8266 have I2C?

ESP8266 chip does not have hardware I²C, so module uses software I²C driver. It can be set up on any GPIO pins including GPIO16 (see below). You have to call i2c. setup on a given I²C bus at least once before communicating to any device connected to that bus, otherwise you will get an error.

How do I connect my I2C LCD screen?

I2C LCD display Pinout

1. GND is a ground pin and should be connected to the ground of Arduino.
2. VCC supplies power to the module and the LCD. Connect it to the 5V output of the Arduino or a separate power supply.
3. SDA is a Serial Data pin. This line is used for both transmit and receive.
4. SCL is a Serial Clock pin.

How to interface 16×2 LCD with ESP8266 NodeMCU?

In this tutorial we interface 16×2 LCD display with ESP8266 NodeMCU without using I2C and with minimum pins i.e. using only 3 pins. To interface LCD with ESP8266 we need at least 6 IO lines but ESP already have very few IO lines, to expand IO lines we use serial to parallel shift register IC 74HC595.

How to setup esp on an I2C LCD?

The basic setup of ESP should be done along with basic setup make the following circuit. We are using I2C LCD backpack here in this tutorial. Mount 16×2 LCD to the I2C LCD backpack. 3. Header File You will need to replace your Liquid Crystal Library with the library available at following link.

How to use 16×2 LCD on Arduino IDE?

This tutorial explains how to use 16×2 LCD on NodeMCU wifi development board using Arduino IDE. 1. Introduction: This tutorial explains how to use LCD for displaying purpose on ESP8266 NodeMCU development board using Arduino IDE. We are using 16×2 character LCD in this tutorial.

Can a 16×2 LCD be used for WiFi?

I have been using 16×2 LCD for displaying the sensors data. 16×2 LCD Physical interfacing with Arduino or Mega or Nodemcu esp8266 wifi module is really a hectic job, as it needs a lot of soldering and needs many IO pins to control a 16×2 LCD.
