read a micro controller data sheet
program your board to do something, with as many different programming languages
and programming environments as possible

Learning after reading data-sheet
Any start with electronics can only done after reading datasheet. Each point is verly well explained. Its helps in understanding process and working of micro controller .
In Final project going to use in Satshakit in which its pin-out and design play very important role.
I can make small wearable sensor base toy which can be made through attiny controller.
I started with https://www.farnell.com/datasheets/1682209.pdf as this belong to Arduino. It was easy for me to understand.
Then after I understand it pins in details and how it can be used.
Below are codes in Embedded Programing
