Driving LCD with ATTiny85 - Wokwi Arduino simulator project

Project details ATtiny85 Simulator

This project demonstrates the ability of the Wokwi Arduino simulator. You can write code on ATtiny85 to drive an LCD2004 (4 rows, 20 column hardware) by yourself. You can learn to program as well as see the code in action. No hardare needed.

Here is the connection diagram for the ATtiny85 Arduino simulator

The code for the project is fairly simple.

#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 20, 4); // set the LCD address to 0x27 for a 16 chars and 2 line display
void setup()
{
lcd.init(); // initialize the lcd
// Print a message to the LCD.
lcd.backlight();
lcd.setCursor(3, 0);
lcd.print("Hello, world!");
lcd.setCursor(2, 1);
lcd.print("LiquidCrystal_I2C");
lcd.setCursor(1, 2);
lcd.print("Running on ATtiny85");
lcd.setCursor(2, 3);
lcd.print("using ATTinyCore");
}
void loop()
{
}
