8. 8Working Procedure:
1. After completing software installation and coding upload
unplug the board.
2. Connect the output pin no 8, 9, 10, 11, 12, 13 of Arduino
board with respective 6 resistors.
3. Connect the resistors with the positive terminal of all the
6 LEDs.
4. Connect the negative terminal of all the LEDs with the
ground pin of Arduino board.
5. Supply power to the Arduino board by USB B wire or
external power port.

10. 10Result
 After making all the connections and uploading the code we found
that the connected LED lights are blinking sequentially as per the
coding.
Precaution:
 All the connections should be tight and proper.
 Handle the Arduino board carefully.
 Check the connection once again before powering the Arduino
board.
 Switch off the Arduino board after performing the Experiment.
