You can find example code for blinking from Arduino example library. Be aware to match your code and pin numbers. LED will not blink If pin numbers in your code doesn't fit with Arduino Uno kit. Arduino must have be connected to your computer to transfer your code for blinking LEDs.



Wire should be need for extension of LEDs. It's impossible to put your LED into the book because LED's legs are too short. Get long wires and combine them to legs by soldering.
