-If you squint your eyes and look at the 1s in that block of code, you can actually see the shape of a heart! A 1 tells the screen to turn a tiny lightbulb on, and a 0 tells it to leave it dark. We save this picture under the name heart_bmp so we can stamp it on the screen later.

 To fix this, we use `millis()`. Instead of going to sleep, `millis()` tells the Arduino to constantly check a stopwatch. It says, "Keep looking at your watch! When 1.8 seconds pass, change the lyrics. When 230 milliseconds pass, make the guy dance!" This is called non-blocking code, and it lets our stick figure dance smoothly while the song lyrics scroll by!

+### 4. The Floating Particle Effects (The Hearts)
+To make the background look like a real party, we stamp our heart_bmp onto the screen. But we want them to float upwards!
+On our screen, a Y-coordinate of 64 is the very bottom, and 0 is the very top.
+
+```cpp
+int heart1_Y = 64 - ((timeNow / 40) % 70);
+display.drawBitmap(120, heart1_Y, heart_bmp, 5, 5, SSD1306_WHITE);

 When people see the little guy dancing on the screen, they usually think it's a tiny video or a GIF. Nope! We are literally drawing him from scratch, 60 times a second, using a digital Etch-A-Sketch.

 Instead of an image, we use math to draw shapes. How does he move? Remember our `millis()` stopwatch? Every 230 milliseconds, a variable called `danceBeat` flips between 0 and 1.
 
 ```cpp
 int danceBeat = (timeNow / 230) % 2;
 int guyY = 25 + (danceBeat == 1 ? -4 : 0);
-```

 I love choreographing dances, so I had to make my stick figure bounce to the exact rhythm of the song. The song is 130 Beats Per Minute (BPM). Doing a little bit of math, that means every 230 milliseconds, a fast, club-style eighth-note beat hits!
 
 Every time the stopwatch hits that 230ms mark, we tell the stick figure to throw his arms up and bounce his Y-coordinate up by 4 pixels.
 
+### 6. The Digital Teleprompter :
+Now for the final piece....drumrollls...the lyrics! This is where you get to customize the code to match your own favorite song.
+
+We use an `if / else if` statement like a movie script. The Arduino checks our millis() stopwatch to see what "phase" of the song we are in, and prints the correct lyrics to the screen!
+
+```cpp
+if (phase == 0) {
+    display.setCursor(0, 8);
+    display.println("If you"); display.println("go hard"); display.println("you gotta");
+  } else if (phase == 1) {
+    display.setCursor(0, 8);
+    display.println("get on"); display.println("the"); display.println("floor");
+  }
+```
