Jhd-2x16-i2c Proteus -

: A chip that converts serial I2C data from a microcontroller (like Arduino or PIC) into parallel data for the LCD.

: Check if you have initialized the correct I2C address in your code (e.g., LiquidCrystal_I2C lcd(0x27, 16, 2); ). jhd-2x16-i2c proteus

If you connect A0, A1, and A2 all to , the 7-bit binary I2C address becomes 0x27 (or 0x3F if using the PCF8574A variant). : A chip that converts serial I2C data
