Blink

=Blink and Daughter Programs=

The Blink program is usually the first program written for the Arduino. It checks to see that the IDE is communicating with the board and that the board is working properly.

There are lots of links to the Blink program: The offical Arduino Tutorial, or this one., or a YouTube guide to setting up the Arduino and running Blink

Once Blink is working there are variations to try:


 * 1) Change the delay so the on and off time are asymmetric.
 * 2) A two LED flasher
 * 3) Without using the DELAY function
 * 4) Use a function to blink the LED
 * 5) Blink 8 LEDs
