Blank Screen: Ensure the "Backlight" command is sent in your code and that the VCC/GND pins are correctly powered in the simulation properties.

: A critical difference noted by users is the I2C address. In Proteus, the PCF8574 address is often , while real hardware typically uses Ease of Use
The JHD2X16I2C is a popular 16x2 character LCD module that uses the I2C (Inter-Integrated Circuit) protocol. Simulating this hardware in Proteus is an excellent way to test your code before building a physical circuit. This guide covers how to set up the simulation, find the necessary libraries, and run your first "Hello World" program for free. Why Use the JHD2X16I2C?
