1. turn-off-led.py
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)

Ket:
 Import RPi.GPIO as GPIO Merupakan modul atau library yang digunakan untuk
mengakses GPIO pin pada raspberry pi.
Import Rpi.GPIO as GPIO Is a module or library that is used to access GPIO pins on
raspberry pi.
 Import time juga merupakan library atau modul yang digunakan untuk pengoperasian
terkait dengan waktu.
Import time Is a module or library that is used to access about the time related.
 GPIO setmode(GPIO.BCM) untuk mengaktifkan sistem penomoran pin GPIO.
GPIO setmode(GPIO.BCM) is command to activating numbering system of GPIO pins.
 GPIO.setwarnings(False) memberitahu python untuk mengabaikan perintah jika pin
GPIO sudah digunakan.
GPIO.setwarnings(False) is command to show the python to ignor notice if GPIO pin has
been used.
 GPIO.setup(16,GPIO.OUT) memberitahu python apabila pin GPIO 16 yang akan
digunakan.
GPIO.setup(16,GPIO.OUT) is command to show the pyhton if GPIO pin 16 has been
used.
 GPIO.output(16,GPIO.HIGH) perintah menyalakan lampu LED

 GPIO.cleanup() perintah untuk memastikan bahwa tidak ada arus listrik di pin GPIO
GPIO.cleanup() is command to makesure if nothing electric current on GPIO pins.
2. blink.py
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(16,GPIO.OUT)
for i in range(3):
GPIO.output(16, GPIO.HIGH)
time.sleep(0.5)
GPIO.output(16, GPIO.LOW)
time.sleep(0.5)
GPIO.cleanup()
Ket:
 For i in range(3) ini adalah perintah perulangan(for loop) yang nantinya lampu LED
akan berkedip sebanyak 3 kali.
For i in range(3) is command to repeat (for loop) which the LED lights will blink 3 times
 Time.sleep(0.5) waktu jeda lampu
Time.sleep(0.5) is break time of the lights

3. traffic.py
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
pinList =[16,20]
SleepTime = 1
for i in pinList:
GPIO.setup(i, GPIO.OUT)
for i in pinList:
GPIO.output(i, GPIO.HIGH)
time.sleep(SleepTime)
GPIO.output(i, GPIO.LOW)
time.sleep(SleepTime)
GPIO.cleanup()
Ket:
 PinList=[16,20] ini adalah perintah List yang akan memberitahu kepada python bahwa pin
GPIO tersebut akan digunakan
PinList=[16,20] this is command to list which give the notice to python if the GPIO pins
has been used.
 SleepTime=1 adalah perintah jeda waktu lampu LED.
SleepTime=1 is command the break time of LED lights.
4. flip_flop.py
import RPi.GPIO as GPIO
import time

pinList =[16,20]
SleepTime = 0.2
for i in pinList:
GPIO.setup(i, GPIO.OUT)
try:
while True:
for i in pinList:
GPIO.output(i, GPIO.HIGH)
time.sleep(SleepTime)
GPIO.output(i, GPIO.LOW)
time.sleep(SleepTime)
except KeyboardInterrupt:
pass
GPIO.cleanup()
Ket:
 flip-flop tidak jauh berbeda dengan traffic hanya saja di flip-flop loop-nya terus
menerus(infinite)
Flip-flop not really different from traffic only in the flip-flop looping continuously
(infinite)
 SleepTiem= 0.2 adalah jeda waktu lampu ketika sedang dioprasikan.
SleepTiem=0.2 is the break time of the lights while being operated.
 Except KeyboardInterrup() mengalihkan loop dan akan diterusakn ke GPIO.cleanup
jika ada intrupsi dari keyboard dengan menekan (CRL+C).
Except KeyboardInterrupt is command to switch the loop and will be continue to GPIO.cleanup if
there is an interruption from the keyboard by pressing (CRL+C)
