If the text is not displayed on LCD I2C, please check the following issues: Adjust the brightness of LCD by rotating potentiometer in the backside of LCD Depending on manufacturers, the I2C address of LCD may be different. Usually, the default I2C address of LCD is 0x27 or 0x3F. Try the...
Before displaying text on the LCD, you need to find the LCD I2C address. With the LCD properly wired to the ESP32, upload the following I2C Scanner sketch. /*** Rui Santos Complete project details at https://randomnerdtutorials.com ***/ #include <Wire.h> void setup() { Wire.begin...

but the same code and concepts work for other Arduino development boards also. Firstly,16×2 LCDinterfacing with Arduino will be discussed. After that, we will also provide examples of 16×4 LCD and I2C LCD interfacing with Arduino.
For knowing more about LCD module JHD162A and its pin functions, read this article:Interfacing 16×2 LCD and 8051 microcontroller. The circuit diagram of interfacing LCD to arduino for displaying a text message is shown below. Circuit diagram – Arduino to 16×2 LCD Module ...
The following diagram illustrates how to hook up an Arduino Uno to an LCD display with the I2C bus adapter: Note how much easier it is to use the I2C connection, which does not consume any of the Arduino Unos 14 digital I/O pins. Since A4 and A5 are being used for the I2C bus the...
However, OLED displays are not without their weaknesses. They tend to consume more power compared to LCD displays, especially when displaying bright or white content. This can be a concern in battery-powered projects. Additionally, OLED displays have a shorter lifespan compared to other types of...
From Text to Track: Retro Racing Game on a 16x2 Character LCD With Arduino: Imagine the nostalgia of playing a classic arcade game on a small, pixelated screen. With a 16x2 character display, you can bring that experience to life in a fun and interactive

You can also use an external LCD display to show these messages, but in all likelihood, you’d use I2C or SPI to communicate with that kind of display (see Chapter 13). The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data ...
