LED Blinking with Arduino Uno - Circuit and Code

Here we are going to write a program to blink an LED for every 500ms. In arduino uno, a LED will be already designed at the pin13, but we are not going to use it. Here we are going to connect an indicating LED to PIN0 through a current limiting resistor.
