Controlling an LCD screen might be difficult due to the restricted pin resources in a microcontroller/microprocessor. With only two pins, serial to parallel adapters such as the I2C serial interface adapter module with PCF8574 chip make the job simple. The serial interface adapter connects to a 16×2 LCD and has two signal output pins (SDA and SCL) for communicating with an MCU/MPU.
