-======Button Shield Kit Tutorial======
-=====Product Description:=====
-[[https://s3.amazonaws.com/digispark/images/m/button.jpg|{{https://s3.amazonaws.com/digispark/images/t/button.jpg}}]][[https://s3.amazonaws.com/digispark/images/m/button.jpg|{{https://s3.amazonaws.com/digispark/images/t/button.jpg}}]]
-This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included.
-=====Parts:=====
-^ Part       ^ Quantity          ^Identification^
-| Button Shield PCB|1| |
-| 10k ohm 1/4 W resistor 1% or 5%|1| Brown - Black - Orange|
-| 12x12mm tactile momentary button|1|
-| 1x40 pin male 0.1" pitch header| 9 pins worth| |
-**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
-Adafruit has this excellent guide that starts with the tools needed and then shows detailed pictures, including some of the common problems that beginners experience (http://learn.adafruit.com/adafruit-guide-excellent-soldering)
-**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:=====
-Empty kit bag (or if using a raw PCB, acquire parts) and verify contents.

-Insert the resistor through the top and solder on bottom of board. Cut excess leads.

-Insert button on top and solder four leads on the bottom.

-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 Button shield is complete!
-=====Programming:=====
-<code arduino>
-void setup() {
-    // Initialize the LED pin as output
-    pinMode(1, OUTPUT);
-    // Initialize the LED pin as input
-    pinMode(5, INPUT);
-}
-void loop() {
-    if(digitalRead(5)==LOW)
-        digitalWrite(1, HIGH);  // Turn the LED on when pressed
-    else
-        digitalWrite(1, LOW);   // Turn the LED off when not pressed
-}
