Connecting an LED to a Raspberry Pi

Having connected the LED, we need to be able to turn it on and off using commands from Python. Start a Python console from the Terminal with superuser access and enter these commands:

$ sudo pythonimport 
RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(12, GPIO.OUT)
GPIO.output(12, True)
GPIO.output(12, False)

LEDs are a very useful, cheap, and efficient way of producing light, but you do have to be careful about how you use them. If they are connected directly to a voltage source (such as a GPIO output) that is greater than about 1.7 volts, they will draw a very large current. This can often be enough to destroy the LED or whatever is providing the current—which is not good if your Raspberry Pi is providing the current. You should always use a series resistor with an LED because the series the resistor is placed between the LED and the voltage source, which limits the amount of current flowing through the LED to a level that is safe for both the LED and the GPIO pin driving it If you want to extend the experiments that you made in the Python console into a program that makes the LED blink on and off repeatedly, you could paste the following code into the IDLE

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(12, GPIO.OUT)
while (True):
 GPIO.output(12, True)
 time.sleep(0.5)
 GPIO.output(12, False)
 time.sleep(0.5)
