Aufbau der Schaltung I

Benötigte Teile:

• Pi
• Steckboard
• 4 Taster
• 4 LEDs
• 4 220 Ohm Widerstände
• Steckbrücken

Aufbau der Schaltung II

• Der fünfte Taster ist optional (Ende-Button)
• Taster-Pins: 4, 17, 27, 22, (MOSI)
• LED-Pins: 18, 23, 24, CS1

Python script I

#!/usr/bin/python
import time
import RPi.GPIO as GPIO
import random
import os
import sys

btnExit = 21 # optional
buttons = [7, 15, 13, 11, btnExit]
leds = [12, 16, 18, 26]

Python script II

def init():
    GPIO.setmode(GPIO.BOARD)
    GPIO.setwarnings(False)
    random.seed()
    for pin in buttons:
        GPIO.setup(pin, GPIO.IN, GPIO.PUD_DOWN)
    for pin in leds:
        GPIO.setup(pin, GPIO.OUT)

def flashLED (cycles):
    for x in range(1, 2*cycles):
        for pin in leds:
            GPIO.output(pin, x%2)
        time.sleep(0.2)
    for pin in leds:
        GPIO.output(pin, 0)
    time.sleep(1.5)

#init()
#flashLED(1)

Python script III

def beep (num):
    GPIO.output(leds[num], 1)
    #os.system("ogg123 --quiet -K1 beep"..num+1..".ogg")
    time.sleep(1)
    GPIO.output(leds[num], 0)
    time.sleep(0.5)

Python script IV

        if (runLoop): flashLED(1)
    print ("GAME OVER")
    GPIO.cleanup()
