Story

After reading a projects by Jeff Larkin, I decided to concentrate more on controlling L.E.D using the Python programming language. Several minutes later I got it, first with Bash and after Python. I followed further instructions regarding using the Python library mentioned in the document by Jeff Larkin and with some very basic Python programming skills, the code worked.

to replicate this project It is necessary for you to read and understand the documentation about the GPIO Pins, about how it works and what you can do with them. First I used my previous experience with Arduino coding, project-board, L.D.R., L.E.D., resistors and the connections.

The project at this time only uses L.D.R. for sensing HIGH or LOW at the GPIO selected and turn On/Off the L.E.D.

Comments are very important, because we can learn more and share it for improvement. I used the VCC-5V port and GND, for input XIO-P0 (L.D.R.) and output XIO-P1 (L.E.D.).

Python

Please, before trying the code, first visit this site https://github.com/xtacocorex/CHIP_IO and follow the instructions for using the GPIO library.

This is a very basic code in Python, the comments import CHIP_IO.GPIO as GPIO # is where the magic being,
import os # is just for use command in terminal
import time # control the time with sleep

This code: time.strftime("%c") # just get the date and time when success the On/Off led

The last line GPIO.cleanup() # clean up the GPIO

Beginners for run the code type in terminal: python filename.py

NOTE: Press Ctrl - C for stop the code.

Comments are important for improve. Have a nice day and enjoy some ice cream.

#-*-coding:utf-8-*-
#!/usr/bin/python

import os # Just for use some commands in the terminal
import CHIP_IO.GPIO as GPIO # Make the magic
import time # Just for sleep and wait some time

GPIO.setup("XIO-P0", GPIO.IN) # port use for INPUT
GPIO.setup("XIO-P1", GPIO.OUT) # port use for OUTPUT

os.system('clear') # Just for presentation
print("Iniciando sistema espere porfavor ...")
time.sleep(3)
print("Comenzando secuencia en 3")
time.sleep(1)
print("2")
time.sleep(1)
print("1")
time.sleep(1)

while(True): # No finish cicle
    if(not GPIO.input("XIO-P0")): # NOT change the value detect in the port
        GPIO.output("XIO-P1", 1) # Turn On LED
        time.sleep(2) # Wait X seconds
        print("Encendido :D " + time.strftime("%c")) # Message with date
    else:
        GPIO.output("XIO-P1", 0) # Turn Off LED
        time.sleep(2)
        print("Apagado :)" + time.strftime("%c"))

GPIO.cleanup() # Clean up the GPIO
