This blog is basically meant to understand some components given in “Arduino MKR1000 IoT Bundle” as they are not labeled.


What this bundle contains- which components with it , can be seen on website but here I give explanation on some parts which can be confusing who will use it first time and use as DIY. 


Attached pics are self explanatory.


Rest , will have to  be careful which end is anode or cathode, or in case of push button which ends connected etc.
