ทุก 5 นาที
หรือ

sleep .5 # Waits 0.5 second.
sleep 5  # Waits 5 seconds.
sleep 5s # Waits 5 seconds.
sleep 5m # Waits 5 minutes.
sleep 5h # Waits 5 hours.
sleep 5d # Waits 5 days.

เล่นกะ GPIO

ทดสอบที่ GPIO 2 

Solution 1 (wiring PI)

sudo apt-get install git-core

git clone git://git.drogon.net/wiringPi 

cd wiringPi
git pull origin
./build

gpio -v gpio -g mode 2 out gpio -g write 2 1 gpio -g write 2 0

Solution 2 (Shell script)

echo 2 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio2/direction
echo 1 > /sys/class/gpio/gpio2/value
echo 0 > /sys/class/gpio/gpio2/value
echo 2 > /sys/class/gpio/unexport

 
Solution 3 (python script)

  $  sudo apt-get install python-dev
  $  sudo apt-get install python-pip
  $  sudo apt-get install python-rpi.gpio 

nano gpio-on.py  

#!/usr/bin/env python
# Turn on GPIO 2
import time
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)
GPIO.setup(2,GPIO.OUT)
GPIO.output(2,GPIO.HIGH)

nano gpio-off.py  
#!/usr/bin/env python
# Turn on GPIO 2
import time
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)
GPIO.setup(2,GPIO.OUT)
GPIO.output(2,GPIO.LOW)

แถม Blink ที่ GPIO 2

import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(2, GPIO.OUT)
while 1:
    GPIO.output(2, True)
    time.sleep(0.2)
    GPIO.output(2, False)
    time.sleep(0.2)

GPIO.cleanup()
