-# Basic GPIO with Python on Resin
-This is a basic example of GPIO control on the Rasperry Pi using Python
-
-We use the GPIO board pin mapping and we also need few LEDs on two sets of GPIO pin:
-
-Set A: 3,5,7,8,10,11,12,13,15 (pin number)
-Set B: 16.18,19,21,22,23,24,26 (pin number)
-
-In this example, the LEDs on two sets will be switched between on and off after one sec. If set A is on then set B is off and vice versa.
-
-All you need to do is :
-
-* clone this repo locally  and cd into the folder.
-* connect some LEDs to two pin sets
-* add the resin remote repo with `git remote add resin git@git.resin.io:myGithubName/myResinAppName.git` , with the correct github and app name, or just copy if from the top right hand corner of your device dashboard on resin.io.
-* now just `git push resin master` wait a minute or so for the code to upload and start.
