Jhd-2x16-i2c Proteus 💯

The JHD-2X16-I2C is a commonly used alphanumeric LCD component in Proteus for simulating 16x2 displays with an integrated I2C (Inter-Integrated Circuit) adapter. Using this model simplifies simulations by reducing the required wiring from over six digital pins to just two. Key Connections in Proteus

7. Simulation Steps in Proteus

  1. Place components – Add microcontroller, JHD-2x16-I2C (use LCD I2C from LiquidCrystal I2C library), and pull-ups.
  2. Wire the circuit – Connect SDA, SCL, VCC, GND.
  3. Load firmware – Double-click µC → Program File → select compiled .hex.
  4. Set I2C address – If using discrete PCF8574, double-click it and set address (e.g., 0x27).
  5. Run simulation – Click play. The LCD should display the message.
