Jhd-2x16-i2c Proteus [better] May 2026

JHD-2X16-I2C is a 16-character by 2-line alphanumeric LCD module featuring a built-in I2C serial interface, commonly used to save microcontroller pins. In this component is often simulated by combining a standard LCD with an I2C I/O expander Handson Technology Key Specifications Interface: I2C (Serial). Resolution: 16 columns x 2 rows. Operating Voltage: I2C Address: Typically defaults to in Proteus simulations, while real hardware often uses Handson Technology Simulation Setup in Proteus

Backlight: In Proteus, you may need to manually power the VDD/VSS pins of the LCD for it to "light up" visually in the simulation environment. jhd-2x16-i2c proteus

To simulate the JHD-2X16-I2C, you must ensure your Proteus library contains the I2C-enabled version of the 16x2 LCD. I2C Serial Interface 1602 LCD Module - Handson Technology JHD-2X16-I2C is a 16-character by 2-line alphanumeric LCD

Code Example

Here's an example code in C using the I2C protocol to display "Hello World" on the JHD-2X16-I2C display: Place LM016L , PCF8574 , ARDUINO_UNO , two 4

The Display: Search for LCD1602 or PC8574 if the integrated JHD model isn't appearing. Often, you manually pair a 16x2 LCD with a PCF8574 I2C I/O expander. Microcontroller: Arduino Uno Go to product viewer dialog for this item. PIC16F877A Go to product viewer dialog for this item.

3.2 Simulation Schematic Setup (Proteus)

  1. Place LM016L, PCF8574, ARDUINO_UNO, two 4.7k resistors, and a 10k potentiometer.
  2. Connect PCF8574:

    6.3 No Simulation Activity

    • Cause: Missing pull-up resistors.
    • Fix: Add 10k resistors connecting the SDA and SCL lines to +5V.
