For this project, besides the Intel Galileo board, power supply unit, and the Grove base shield, you'll need the following components:
Grove LCD RGB Backlight: It is a part of the Grove Starter Kit Plus, and is a 16 x 2 LCD screen. It brings more functionalities than most typical LCD screens. Besides allowing us to print two rows of 16 characters at most, the backlight can also be RGB customizable.

It also supports user-defined characters and communicates using the I2C protocol (https://learn.sparkfun.com/tutorials/i2c) through only two IOs.

It can be connected to a digital output to simply emit sound, or it can be connected to a PWM output and play different tones.
