-**Resistor Values:** For more information on how to identify the value of the resistors we recommend these sites:
-A nice simple resistor calculator: http://www.ealnet.com/m-eal/resistor/resistor.htm
-A comprehensive article on identification: http://www.diyaudioandvideo.com/Electronics/Color/
-**Soldering:** If you are new to soldering we recommend the following tutorials:
-Soldering Basics (http://www.sparkfun.com/tutorials/106) and Soldering Crash Course from the folks at Sparkfun (http://www.sparkfun.com/tutorials/354).
-How to solder from the Curious Inventor: http://store.curiousinventor.com/guides/How_to_Solder
-**We assume for these assembly instructions that you know the basics of thru-hole soldering. If you don't check out the links above, these boards are very easy to solder - we promise!**
-=====Assembly:=====
-{{https://s3.amazonaws.com/digispark/tutorials/rgb/s1.jpg}}
-Empty kit (or if using a raw PCB, aquire parts) bag and verify contents.
-**Note for Kickstarter Backers and Pre-orders:** Headers are not included in each kit bag, but the entire order came with more than enough headers for all kits.
-{{https://s3.amazonaws.com/digispark/tutorials/rgb/s2.jpg}}
-Solder resistors one at a time. Match the value of resistor with the number written within the resistor outline on the board. Solder the leads and clip off the excess. Repeat for all resistors.
-{{https://s3.amazonaws.com/digispark/tutorials/rgb/s1.jpg}}
-When inserting the LED into the board ensure the longest lead of the LED goes through the hole marked ground - this ensure you ahve the LED oriented properly. Solder the LED leads and clip off the excess.
-{{https://s3.amazonaws.com/digispark/tutorials/rgb/s1.jpg}}
-Cut a length of male headers 6 pins long and one 3 pins long. Insert into corresponding positions (on the bottom of the board) and solder each pin.
-**Tip:** Inseting the headers into a breadboard and then placing the board on top can make this process easier.
-**Note:** If you are using stackable headers, use them here instead of the standard male headers.

-Your RGB shield is complete!
-=====Programming:=====
-**Note:** The programming sections assumes you've installed the Arduino IDE and the Digispark Add-ons: [[SoftwareSetup]]
-The RGB shield uses the following pins to control the LEDS:
-Pin 0 -> Red
-Pin 1 -> Green
-Pin 2 -> Blue
-Turning a color on or off is as simple as this:
-<code arduino>
-void setup() {
-  // initialize the LED pins as outputs
-  pinMode(0, OUTPUT);
-  pinMode(1, OUTPUT);
-  pinMode(2, OUTPUT);
-}
-void loop() {
-  digitalWrite(0, HIGH);   	// turn the Red LED On
-  delay(1000);              // wait for a second
-  digitalWrite(1, HIGH);   	// turn the Green LED On
-  delay(1000);              // wait for a second
-  digitalWrite(2, HIGH);   	// turn the Blue LED On
-  delay(1000);              // wait for a second
-  digitalWrite(0, LOW);    	// turn the Red LED off
-  digitalWrite(1, LOW);     // turn the Green LED off
-  digitalWrite(2, LOW);     // turn the Blue LED off
-  delay(1000);              // wait for a second
-}
