How to simulate the LCD1602 Character Display (I2C) in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the LCD1602 Character Display (I2C) (catalog type lcd1602).
  3. Connect GND and VCC to the supply and ground of the board.
  4. Connect SDA and SCL to the I²C data and clock pins of the board.
  5. Run the firmware. It finds the part on the I²C bus and reads and writes it as on hardware.
