That's my current structure:
The short metal of the LED (-) is connected to GND, and the longer (+) is in the port 26. This black "thing" (I don't know the name) is connected to my Pi B+ by a gray cable.
import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BOARD) GPIO.setup(26, GPIO.OUT) delay = 2 def turnon(pin): GPIO.output(pin, 1) return def turnoff(pin): GPIO.output(pin, 0) return while(True): turnon(26) time.sleep(delay) turnoff(26) time.sleep(delay)
I run this code as root (because it orders me to do that). The problem is that when I execute this code nothing happens. I don't get any errors and the LED doesn't blink.
The Pi I bought was this one: http://www.amazon.com/CanaKit-Raspberry-Ultimate-Starter-Components/dp/B00G1PNG54
