Parameters
- x is a number that means the horizontal spot on the LED screen (from left to right: 0, 1, 2, 3, or 4)
- y is a number that means the vertical spot on the LED screen (from top to bottom: 0, 1, 2, 3, or 4)
If a parameter is out of bounds (a value other than 0 to 4), then this function will do nothing.
~hint
The LED screen is a solid square of LEDs with five LEDs on each side.
To learn more about how you number the LEDs with x and y
coordinates, see LED screen.
