LEDPin = 11 # pin11

GPIO.setmode(GPIO.BOARD) # Numbers GPIOs by physical location

GPIO.setup(LEDPin, GPIO.OUT) # Set LEDPin's mode as output

GPIO.output(LEDPin, GPIO.HIGH) # Set LEDPin as high(+3.3V) to turn off the led

try:

while True:

print '...led on'

GPIO.output(LEDPin, GPIO.LOW) # led on

time.sleep(0.5)

print 'led off...'

GPIO.output(LEDPin, GPIO.HIGH) # led off

time.sleep(0.5)

except KeyboardInterrupt: # When 'Ctrl+C' is pressed, the following code will

be executed.

GPIO.output(LEDPin, GPIO.HIGH) # led off

GPIO.cleanup() # Release resource

Step 3: Run

sudo python led.py

You should see the LED blinking. Press Ctrl+C to terminate the program.
