Step 5: Assemble and Arrangement

1) Assemble the whole unit in a box, use battery for Linkit one so even power off the time remain the same.

2) I used the box already i used for Intelligent Calling bell.

3) Now arrange. For demo purpose i arrange all in the floor.

4) For real time use connect all in a secret place and just give connection to the speakers and lights.

5) Connect the Speakers to the audio jack of the linkit one board.

6) Connect the party light to the power supply through Relay control board com and no.

(At the last minute my single 5V relay module not working so i use my 4 12V relay module)

7) All done set the current time and Alarm time.

Step 6: Setup Alarm

1) Use the android app u can able to change the current time and set time.

2) Use the Push button over the board to change between the menu between set time and cut time.

3) After Alarm start and music play if u want to stop it use the same push button.

4) See how to change and set in the video.

Step 7: Lets Rock and Roll

I plan to demo the New year night party. So set current time to 31/dec/2015 23:55 and set the alarm time to 01/jan/2016 00:00. Switch off all the lights see how it works. I load a soft music, and also its a night time 3.00 time i put the volume very low. All working fine see the video. Plan to use it for up coming parties.

But most surprise one is assemble all in a closed box and put a gift near the bulb. Close the box. Act like u don't remember ur wife birthday and act like fall as sleep. Sharp at mid night the Song start when she open the box lights fill the room and ur special gift inside the box.
