Week 1.
Тест.
Задача.
Setup your Raspberry Pi by usingNOOBSto install Raspbian on the micro SD card. Boot your Raspberry Pi to the desktop and take a picture (with a regular camera/phone) of the desktop. Submit the picture as evidence that you completed the task.

Week 2.
Тест.
Задача.
Boot the Raspberry Pi and install the “scrot” program to take screen shots. You can install it by typing “sudo apt-get install scrot” in a terminal window. Use the scrot program to take a screenshot of your Raspberry Pi.

Week 3.
Тест.
Задача.
Write a Python program that prompts the user to input 3 numbers, one at a time. The Python program should put the numbers in a list, sort the list, and print the sorted list. Executing the program should produce results something like this:
Enter a number:
5
Enter a number:
4
Enter a number:
3
3, 4, 5
>>>
Hints:
Python lists have a built-in sort() method that you could use. The input() function will accept input from the user at the command line.
Решение:
x = int(input("Enter a number: "))
y = int(input("Enter a number: "))
z = int(input("Enter a number: "))
numbers = [x, y, z]
print(sorted(numbers))

Week 4.
Тест.
Задача.
Build a circuit using your Raspberry Pi that causes an LED to blink when a push button is NOT pressed. However, the LED should stay on continually when the push button IS pressed.
import RPi.GPIO as GPIO
from time import sleep
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
pinNumLED = 5
pinNumBTN = 16
GPIO.setup(pinNumLED,GPIO.OUT)
GPIO.setup(pinNumBTN,GPIO.IN)
while True:
if (GPIO.input(pinNumBTN)):
GPIO.output(pinNumLED,GPIO.HIGH)
else:
GPIO.output(pinNumLED,GPIO.HIGH)
sleep(0.2)
GPIO.output(pinNumLED,GPIO.LOW)
sleep(0.2)
