If you're not already experienced with the Trinket microcontroller, take the time to set it up and make sure you can load working code onto it. The "Introducing Trinket" guide will walk you through everything you need to know to get it set up and working.

You will also need a good drawer or door to install the lock. A "good" drawer means:
  • At least 2 1/4" deep. (57mm)
  • A wood front at least 3/8" (10mm) thick.
  • Something that you can drill holes into without getting into trouble.
This project demonstrates installing it on a drawer but you could easily put it on the inside of a cabinet door.
