Proteus does not always have a pre-made schematic symbol specifically named "JHD-2x16-I2C" in all library versions. Therefore, the simulation is constructed using the standard parallel LCD and an I2C expander component.
The "JHD-2x16" refers to a standard LCD manufactured by JHD (Jinghua Display). jhd-2x16-i2c proteus
: If the simulation runs but the screen is blank, verify the I2C address. Use an I2C Scanner sketch within Proteus to confirm the virtual address. Library Mismatch Proteus does not always have a pre-made schematic
While the exact JHD-2x16-I2C model may not exist by name in every Proteus version, you can fully simulate it using or an I2C LCD pre-built model . This simulation works perfectly for Arduino, PIC, AVR, and 8051 projects without real hardware. and 8051 projects without real hardware.
