Abstract: Arduino Uno is a minimum system board that use atmega 328p as a microcontroller IC (Integrated Circuit). Arduino Uno has 20 output pins. The running out of the pins owned by the Arduino Uno makes it cannot control many LCD, such as 3 LCDs that require 21 pins. With the lack of the Arduino Uno, this study is focusing on expand output pin of Arduino Uno so that it has 32 additional pins by making use of internal SPI communication. This expansion on the Arduino Uno uses 2 MCP23S17. MCP23S17 one to control LCD 1 and LCD 2 while MCP23S17 two to control LCD 3 and LCD 4. The method used in this study is a quantitative method. Data register that used to support SPI communication in this study was obtained from the MCP23S17 datasheet. The results of this study show a table of register data SPI set address that can be used to control the expansion pin on MCP23S17 and pictures of 4 LCD control display.
