I wired a shift register (74HC595 IC) to the Arduino Uno. As I gave power to the Arduino, the green and yellow leds on Arduino board stop shining. What are these LEDs for? And what is reason behind it?

Some simple instructions to post your question:

  1. Be respectful. Everyone here helps because they enjoy helping, not because it's their job.
  2. Be specific! eg "How do I change the table background colour?" instead of "My code doesn't work. Help?"
  3. Tag your question appropriately.
  4. If you have a school or university assignment, keep in mind that your teacher or lecturer is also reading these forums.
  5. Do not remove or empty a message if others have replied.

Your question may be edited or retagged by other users or moderator. Anything inappropriate will be removed from the post or removed the post.
