Place a on the SCL line and connect it to VCC (Pull-up).
If you tell me which you are using or if you need the specific download link for the library files, I can provide more tailored instructions.
Many electronics community forums and GitHub repositories offer free JHD2X16I2C models. jhd2x16i2c proteus free

If you want, I can: provide a ready-to-use Arduino .ino sketch, a Proteus parts list with exact component names, or search for a free PCF8574 Proteus model and give download instructions. Which would you like? Place a on the SCL line and connect it to VCC (Pull-up)
Ensure the VSS/GND pin of the display is linked to the ground terminal, and VDD/VCC is linked to a +5V power source node. Step 3: Writing the Firmware
