LM016L or AMPIRE16X2 (Standard 16x2 alphanumeric displays).
Note: Pins D0, D1, D2, and D3 on the LM016L LCD should be left floating (unconnected), as the module operates strictly in 4-bit mode over I2C. Arduino Firmware Configuration

Most tutorials cover the basics, but they often miss the specific simulation quirks that cause projects to fail in Proteus. jhd2x16i2c proteus exclusive
Need the actual Proteus Design File (.pdsprj)? Simulate first with the steps above – 90% of "not working" cases are missing pull-ups or contrast adjustment.
Whether you're an engineering student learning microcontroller programming, a hobbyist prototyping a new gadget, or a professional engineer validating a design before PCB fabrication, the techniques outlined in this guide will save you hours of debugging time and give you confidence in your simulations.
Connect the components as follows:
) and search for "LCD1602" or "PCF8574". While some versions of Proteus include the JHD2X16I2C directly, you often need to pair a standard (16x2 LCD) with a I2C I/O expander to replicate its behavior.
Showing battery voltage, obstacle detection status, or motor speed.
However, the JHD2X16I2C often poses challenges in simulation, making an "exclusive" or specialized approach necessary to get it running properly in Proteus. LM016L or AMPIRE16X2 (Standard 16x2 alphanumeric displays)
Mastering the JHD2x16i2c LCD in Proteus: A Comprehensive Guide
Use the LiquidCrystal_I2C library if you are programming in the Arduino IDE.
Tie the address pins () of the PCF8574 to GND to establish the default hex address 0x27 (or tie them to VCC for 0x3F , depending on your library choice).
