📌 Code Examples & Usage – 16×2 I²C LCD (RGB Backlight and RGB Character Versions)

📋 Important – Two Versions Available

This product is available in two different RGB variants. Please ensure you follow the example that matches your version.

🔹 Version A – RGB Backlight LCD

  • Standard black characters

  • RGB backlight only (colour behind the text)

  • Characters themselves are not coloured

  • Most common version

🔹 Version B – RGB Character LCD

  • Characters themselves are RGB coloured

  • Backlight is typically fixed or non-RGB

  • Each character colour is controlled electronically

  • Less common, more “specialty” display

Both versions use I²C (IIC) and require only 4 wires.

🔌 Wiring (Same for Both Versions)

LCD Pin Arduino Uno ESP32 (Example)
VCC 5V 5V
GND GND GND
SDA A4 GPIO21
SCL A5 GPIO22

✔ ESP32 uses 3.3 V logic and is compatible
✔ Power at 5 V for best brightness and contrast

📦 Library Installation (Arduino IDE)

Install the following libraries:

  • LiquidCrystal_I2C

  • Wire

Some RGB variants also require direct I²C control of the backlight or character driver (examples below).

🅰️ Version A – RGB Backlight LCD

Description

  • Text is fixed colour (black)

  • Background colour is RGB

  • Two I²C addresses are commonly used:

    • LCD controller: 0x27 or 0x3F

    • RGB controller: 0x62

🧪 Arduino Example – Text + RGB Backlight

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);
#define RGB_ADDR 0x62

void setBacklight(uint8_t r, uint8_t g, uint8_t b) {
Wire.beginTransmission(RGB_ADDR);
Wire.write(0x04);
Wire.write(r);
Wire.write(g);
Wire.write(b);
Wire.endTransmission();
}

void setup() {
Wire.begin();
lcd.init();
lcd.backlight();

lcd.setCursor(0, 0);
lcd.print("AuscomTech");
lcd.setCursor(0, 1);
lcd.print("RGB Backlight");

setBacklight(0, 255, 0); // Green background
}

void loop() {
}

🌈 Backlight Colour Examples

setBacklight(255, 0, 0); // Red
setBacklight(0, 255, 0); // Green
setBacklight(0, 0, 255); // Blue
setBacklight(255, 255, 255); // White
setBacklight(0, 0, 0); // Off

🅱️ Version B – RGB Character LCD

Description

  • Characters themselves are RGB coloured

  • Background/backlight is usually fixed

  • Often uses a different controller

  • Colour control is applied per character or per screen

⚠ Exact behaviour depends on the onboard RGB driver IC.

🧪 Arduino Example – RGB Characters (Generic Method)

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup() {
Wire.begin();
lcd.init();
lcd.backlight();

lcd.setCursor(0, 0);
lcd.print("RGB TEXT LCD");

lcd.setCursor(0, 1);
lcd.print("Colour Demo");
}

void loop() {
// Character colour control is handled internally by the module
// and may be fixed or preset depending on the version.
}

📌 Note:
RGB character modules may:

  • Use fixed preset colours

  • Cycle colours automatically

  • Require a specific vendor library

If colour control is not responding, the display is still functioning correctly — the colour behaviour is module-specific.

🔎 Finding I²C Addresses (Highly Recommended)

Because these LCDs may use one or two I²C addresses, run this scanner if anything doesn’t work:

#include <Wire.h>

void setup() {
Wire.begin();
Serial.begin(9600);
}

void loop() {
for (byte addr = 1; addr < 127; addr++) {
Wire.beginTransmission(addr);
if (Wire.endTransmission() == 0) {
Serial.print("I2C device at 0x");
Serial.println(addr, HEX);
}
}
delay(5000);
}

Common results:

  • LCD: 0x27 or 0x3F

  • RGB controller: 0x62

🧠 Tips & Troubleshooting

✔ Blank screen → adjust contrast potentiometer
✔ Text visible, no colour → check RGB I²C address
✔ ESP32 → always call Wire.begin(SDA, SCL)
✔ Wrong colours → try different RGB values
✔ Nothing detected → run I²C scanner
