Make sure you will use an Arduino MEGA because the UNO don't have enough memory for this project. Then get that serial controlled 7 segments display module with 8 digits. The DF player and a SD micro card of 4 or below 4Gb. Get the WS2812 LED strip, the one with 30 LEDs per meter and get 5m so 150 LEDs because we need 128. You'll need a power supply of 5V and at least 2 amps of current. You could also buy an amplifier and place that between the DFplayer nand the speaker.
