A bag of electronic components is included with your kit. You will use these parts to build circuits in almost every chapter of this book. This kit is also available separately as the Boe-Bot and Shield-Bot Refresher Pack.

Note: Your Infrared Receivers may look different, since suppliers change over time.  If you ever need replacements, be sure to order the Infrared Receiver for Boe-Bot and Shield-Bot (#350-00039).
