Core Lab Week3 Assignment(A New Game)
The name of object: Super flash
Before a game starts:
Waiting for players to reset the instrument by pressing the reset button. The four blue and yellow LED lights are turned on.
During the game:
If the yellow LED light turns on when the player presses the button, then the player scores one point. After pressing the game button when then light flashes in the middle of the 5 lights, the buzzer also makes a sound, and the game will speed up and continue.
If the blue LED lights are turned on when the player presses the button, it indicates that the game is over.

ii)A sample Fritzing schematic
iii)function or library is needed to make it work
Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:
