Connect a 4.7kΩ pull-up resistor from the SDA line to VCC (+5V).
Most Arduino libraries (like the popular LiquidCrystal_I2C by Marco Schwartz) default the LCD address to 0x27 .
Tie the address pins () of the PCF8574 to Ground (GND). This fixes the hardware I2C address to 0x20 (or 0x27 depending on the exact chip variant model). 3. Wire the PCF8574 to the LM016L LCD jhd2x16i2c proteus exclusive
Here is an exclusive guide to setting up the JHD-2X16-I2C simulation accurately. 1. The Right Library is Everything Most users fail because they use the default LiquidCrystal_I2C library. For the JHD2X16I2C, you must use the DFRobot_RGB_LCD1602 library or the DF Robot LCD Point H

The PCF8574 translates the I2C signals from your MCU into parallel data for the LCD. This fixes the hardware I2C address to 0x20
The "deep story" of this component isn't a narrative tale, but rather the technical struggle many engineers face when trying to simulate I2C-enabled displays, which are notorious for being difficult to configure . The Technical "Deep Story"
