Your Annoy-O-Matic is coded and ready to be deployed! Plug in the AAA battery pack. Test it out by turning on the battery pack’s ON/OFF switch. Your first chosen sound or song will play.
In order to neaten up the package a bit, you can use double stick foam tape to attach the Gemma M0 to your battery box.
You can hide the Annoy-O-Matic in a drawer or box as it is -- but if you want to get even more sneaky, add a magnet so it can be surreptitiously attached to metal objects, such as the underside of a desk...
Deploy the Annoy-O-Matic!
Turn on the power switch and listen to the first instance of the sound play -- it is now armed and ready to go off again in five minutes, or whatever you set for your interval time. The longer the interval, the harder it will be for them to figure out the source of their annoyance!!
Hurry up and hide the Annoy-O-Matic somewhere within earshot of your victim and wait for the fun to begin!
