If you want as a functional simulation without paying : ✅ Use Proteus trial + community library ✅ Or switch to Wokwi / SimulIDE ❌ Don’t look for cracked Proteus – not worth the risk.

: Available via the Arduino IDE Library Manager ( Tools > Manage Libraries ).

display in Proteus, you need to set up an I2C-enabled 16x2 LCD module and use a compatible library, as standard libraries often fail with this specific controller. 1. Set Up the Component in Proteus

// Set the LCD address to 0x27 for a 16 chars and 2 line displayLiquidCrystal_I2C lcd(0x27, 16, 2);

You must download a third-party library or simulate using two separate components: an LM016L + PCF8574.
