The actual round is displayed in the Python Shell window

for i in range(round):

LEDOn(color[i], 1)

Now the program performs the pattern that the player has to remember. Depending on the actual number of

rounds, LEDs light up one after the other in the random colours according to the list

colour which was set

up in the program previously. Since the counter

round starts with 1, one LED is already lit in the first round.

To illuminate the LED, the function

LEDOn() is used that uses as the first parameter the colour from the

corresponding list position, the second parameter lets each LED light up for one second.

for i in range(round): When the colour pattern has been played, another loop starts and here the player

has to reproduce the memorized pattern using the buttons.

button = push() This calls the function Push() with a waiting period until the player has pressed a button.

The number of the button pressed is stored in the variable

button

LEDOn(button, 0.2) When a button is pressed the associated LED is lit for 0.2 seconds.

if(button != color[i]): If the last button pressed does not match the colour at the corresponding

position in the list, the player has lost. The operator

!= stands for not equal. Here also <> can be used.

print “Lost!"

print “You have made it to round", round – 1, “success"

The program displays on-screen that the player has lost and the number of rounds managed to play. The

number of rounds passed is one less than the current round counter.

for j in range(4):

GPIO.output(LED[j], True)

As an optically visible sign all LEDs are switched on ...

for j in range(4):

time.sleep(0.5); GPIO.output(LED[j], False)

... Then one after another at intervals of 0.5 seconds they are turned off again. This results in a significant

reduction effect.

ok = False The variable ok that identifies whether the player is still playing is set to False ...

break ... and the loop is aborted. The player can no longer press a button. The first mistakes ends the game.

if(ok == False):

break

If ok is on False the outer loop is aborted and no other rounds follow.
