Bright your LED with Raspberry PI
In Last blog i setup Raspberry PI, Initially i planned to not write blog for this example as internet already provided lot of examples and tutorial for flashing LED with Raspberry PI. but during my experience to test with PI4J i tried to explain things in my way.
This will be step by step tutorial starting with connecting the cables then some explanations and writing code in PI4J.
The Raspberry Pi is single board computer which is very good for prototyping and it has 40 pins that can be configured for General Purpose I/O (GPIO) and more.
First fit T-shaped Cobbler breakout board via a ribbon cable on breadboard. This is easier and safer than working directly on Raspberry Pi.(Like showed in Pic on left side)
For basic concept i will recommend following link
