title: How do I make an Arduino run a specific script every time it boots?
body: <p>I currently have an Arduino Uno, (version 1.3) with a pn532 NFC shield manufactured by Adafruit.</p>
  
  <p>I was wondering if there was a way to make it so that the Arduino runs a particular code I have written every time it boots? Does this involve playing around with the bootloader?</p>
  
  <p>I have no prior experience with Arduinos, and my coding knowledge is fairly basic (have only really coded in Python), so suggestions that start from the absolute ground level would be highly appreciated! :)</p>
