I have Raspberry Pi B+ and i just bought 8 channel relay. i successfully connected but i really need a simple code to run it to trun on and off the channel relay?
would you please help me

Dear: Simsim
You should know that it is fairly simple using GPIO. As a matter of a fact I used GPIO to make an LED blink Morse code. You should know the code is simple. Try this in python.
import RPi.GPIO as GPIO import time
You should know that this basically imports GPIO and time so we can use the GPIO board and use time to control the amount of GPIO we use but it does not do anything else. Try this to turn on the board.
GPIO.setmode(GPIO.BOARD)
This will turn on the board try this to create an output.
number = 37 GPIO.setup(number,GPIO.OUT) GPIO.output(number,True)
Of course there are many ways to create an output but this is the easiest for me anyways. What the the code does is turns on GPIO 26 to ouput high. to create an input do this.
GPIO.setup(GPIO.BCM) number = 37 GPIO.setup(number, GPIO.IN) GPIO.input(number, True)
To create a bidrectional (or IO) I don't know. I am sorry but I can't answer that. Next you will need to look at this diagram to help you with your code. Also you should know to look for the diagram relavent to your raspberry pi.
Good luck and bye..

PS in case you are wondering the pinout above is for B+ the pinout below is for A.
