'''5.''' Now that this works, you will need to add the other directions for the joystick. Where you have {{fname|1=if event.key == K_DOWN:}} in your code, you can also use:
* {{fname|K_UP}} - Touche vers le haut
* {{fname|K_DOWN}} - Touche vers le bas
* {{fname|K_LEFT}} - Touche vers la gauche
* {{fname|K_RIGHT}} - Touche vers la droite
* {{fname|K_RETURN}} - Touche "''retour clavier''" ou "''entrée''".
'''6.''' We can add a section for each direction to complete your code:
<nowiki>import pygame
from pygame.locals import *
from sense_hat import SenseHat
pygame.init()
pygame.display.set_mode((640, 480))
sense = SenseHat()
sense.clear()
running = True
x = 0
y = 0
sense.set_pixel(x, y, 255, 255, 255)
while running:
for event in pygame.event.get():
if event.type == KEYDOWN:
sense.set_pixel(x, y, 0, 0, 0) # Black 0,0,0 means OFF
if event.key == K_DOWN and y < 7:
y = y + 1
elif event.key == K_UP and y > 0:
y = y - 1
elif event.key == K_RIGHT and x < 7:
x = x + 1
elif event.key == K_LEFT and x > 0:
x = x - 1
sense.set_pixel(x, y, 255, 255, 255)
if event.type == QUIT:
running = False
print("BYE")</nowiki>
'''7.''' When you run your code, you should now be able to move the pixel point anywhere on the matrix.
