Proteus — Jhd-2x16-i2c

void loop() { // Nothing here for static text }

However, in its default library. If you search for it, you won't find it. So, how do we simulate it? We build it.

void setup() { lcd.init(); // Initialize the LCD lcd.backlight(); // Turn on backlight (if wired) lcd.setCursor(0, 0); lcd.print("JHD in Proteus!"); lcd.setCursor(0, 1); lcd.print("I2C works fine!"); } jhd-2x16-i2c proteus

Have you ever run out of GPIO pins on your Arduino? Or maybe you just hate soldering 16 jumper wires just to display "Hello World"? Enter the JHD-2x16-I2C module.

Now go ahead—simulate your next IoT project without wasting a single physical wire. void loop() { // Nothing here for static

In the physical world, JHD makes standard 16x2 LCDs. The "I2C" version comes with a small backpack (PCF8574 chip) soldered to the back. It converts the parallel 16-pin interface into just 2 wires (SDA and SCL).

In this tutorial, I’ll show you how to simulate a 16x2 character LCD using the I2C protocol (PCF8574 backpack) inside . The best part? You don't need a physical LCD, a soldering iron, or even pull-up resistors. Let's dive in. We build it
