test pin 17
<code>
gpio -g mode 17 out
gpio -g write 17 1
sleep 2
gpio -g write 17 0
</code>

python
<code>
import RPi.GPIO as GPIO
import time

GPIO.cleanup()
GPIO.setmode(GPIO.BOARD)

channel=11
GPIO.setup(channel, GPIO.OUT)

while True:
    GPIO.output(channel, GPIO.HIGH)
    time.sleep(1)
    GPIO.output(channel, GPIO.LOW)
    time.sleep(1)
