    GPIO numbering system in RaspberryPi

    elm079

      Hello,

            I've recently acquired an adeept starter kit to try and teach myself some python language while building cool stuff. Getting to know my Pi's GPIO pins has been a whole new experience for me. Although very fun I've come across a bit of a dilemma in the coding process. In one lesson to build a relay the code asks me to declare a variable to use #pin11 which is GPIO17 on my Pi.

      But when I physically build the circuit the instructions have me connect to GPIO18. Strange thing is when I run the code the program executes perfect. To test how I altered the code to output from pin12(GPIO18) instead of pin11(GPIO17) and the program still executed. Any reason why?
