Secript Python
1. turn-off-led.py
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(16,GPIO.OUT)
GPIO.output(16,GPIO.HIGH)
time.sleep(2)
GPIO.output(16,GPIO.LOW)
GPIO.cleanup()
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

3
GPIO.output(16,GPIO.HIGH) is command to turn on of the LED lights.
 Time.sleep(2) Perintah untuk menjeda nyala lampu LED
Time.sleep(2) is command to interrupt turn on of the LED lights.
 GPIO.output(16,GPIO.LOW) perintah untuk mematikan lampu LED
GPIO.output(16,GPIO.LOW) is command to turn off the LED lights.
 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 time
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

4
3. traffic.py
import time
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)
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 time

5
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)
GPIO.output(i, GPIO.LOW)
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)
