-======Button Shield Kit Tutorial====== 
- 
-=====Product Description:​===== 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​button1.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​button1.jpg}}]][[https://​s3.amazonaws.com/​digispark/​images/​m/​button4.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​button4.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. ​ 
- 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​button1.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​button1.jpg}}]] 
- 
-Insert the resistor through the top and solder on bottom of board. Cut excess leads. 
- 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​button2.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​button2.jpg}}]] 
- 
-Insert button on top and solder four leads on the bottom. 
- 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​button3.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​button3.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 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 
- 
-} 
-</​code>​
