• 1. The pixels can light up one by one.

• 2. We can put the interval time for the pixel to light up in the funcKey function. The input is the light interval.

• 3. We can change the color of the light using the color function. When we input the number <=10, the LEDs will get rid of the green light in RGB, only showing the Red and Blue pattern.
