		+	== LED Strip ==
		+	Current limiting resistors as shown in circuit may not be needed if using LED strip instead of single LED.
		+	LED strip usually has 2 wires: one for supply (12V) and the other for ground. If you have an RGB LED strip, it will have 4 wires Power supply, Red, Green and Blue. All the Red, Green and Blue are Grounds. Ground the color that you want to use: example: Ground RED to turn on LED strip as RED. Ground all the three colors to get white.
		+
		+	Do NOT use strips that are longer than a meter. cut them to required length before using.
		+
		+	== Power Supply ==
		+	Purchase a 12V/2A adaptor. Cut the power cord at a suitable length to reveal Power and ground lines. Use wire wrapping to connect these lines to the circuit.
		+
		+	Alternate way: Purchase this (http://www.adafruit.com/product/368) component and use wires to connect to the + and - terminals .

	Note that your board contains wireless mesh network allowing you to freely connect many boards together and they can all communicate with each other. This can be useful if you wish to earn extra credit by interacting with multiple boards. For example, a motion sensor on one board can turn on the lights on multiple boards. The API is documented at your board's wikipedia page.
