Tutorial: How to Use the LCD 1604 5V Blue Screen 16×4 Arduino Compatible Module

The 1604 5V Blue LCD Screen Module is perfect for displaying information on Arduino projects. Ideal for beginners and intermediates, it allows text and small image display.

What you need

• 1604 LCD Module
• Arduino
• FPC Cable (provided)
• 10kΩ Pull-up Resistor (check datasheet)

Steps

1. 1. Connect the LCD module to the Arduino using the provided FPC cables. Check the datasheet for the correct pins.
2. 2. Connect the pull-up resistor between VCC and GND on the LCD module.
3. 3. Download the Graphics LCD library for Arduino from the Arduino website.
4. 4. Open the Sketch and include the library: `#include `.
5. 5. Initialize the LCD: `GLCD myGLCD;`.
6. 6. Create a function to display text: `void printText(char *message) { myGLCD.locate(0, 0); myGLCD.print(message); }`.
7. 7. Call the function in `loop()`: `printText(“Hello, Arduino!”);`.
8. 8. Upload the Sketch to Arduino.

Example code

void loop() { stampaTesto("Ciao, Arduino!"); delay(2000); }

Mini project

Create a simple stopwatch. Display elapsed time in minutes and seconds on LCD.

Common mistakes

• Omitting the pull-up resistor can cause malfunctioning issues.
• Incorrectly connecting the LCD module pins can damage the display.
• Do not use an unofficial library that may not work correctly.
• Ignoring the Arduino code update can cause display errors.

Recommended accessories
