Story

Add life to any old poster at home using a Spark Core, which is postage stamp-sized Wi-Fi module for interacting with physical things and Neo-pixels which are tiny smart LED's.

In addition add a piezo buzzer to the circuit, if the poster is in your teenager room so that you can summon him/her down when the dinner is ready.

As part spark powered command center code your teen will has 3 warning before he/she is Grounded !!

#Warning 1 - NeoPixel LEDs on Rocket are yellow and there is one beep

#Warning 2 - NeoPixel LEDs on Rocket are Red and there are two beep

#Warning 3(final warning) - Rocket's eyes are Red and other 3 NeoPixels below his head keep changing color and the buzzer keep's beeping continuously ..

#And you can Reset at any point in time, if he/she is at the dinner table.
