You've been bugged!
Someone hid a tiny noise-making device near you. Yes, those random beeps? That's us. Congratulations on finding it.
Bugger is a tiny open-source prank device. Powered by a single coin cell battery, it beeps at random intervals for months. It has 6 devious modes to choose from.

Getting Started
Insert the Battery
Pop a CR2032 coin cell into the battery holder on the bottom of the board (the side opposite the QR code and components).
Make sure the positive (+) side faces up (away from the board) — line it up with the + marker on the battery shield.
Choose Your Mode
When you insert the battery, the device beeps N times to tell you the current mode (e.g. 3 beeps = Mode 3).
Press the button (SW1) within 5 seconds to cycle to the next mode. Each press confirms the new mode with the matching number of beeps.
Don't press anything for 5 seconds and a long beep locks in your selection. The mode is saved to flash — it sticks even if you remove the battery.
Press the button at any time during operation to go back to mode selection.
Deploy
The tab with a hole on the left side of the board is a mounting point — use it with a lanyard, piece of string, or zip tie.
The cutout next to it is where the piezo buzzer sits (mounted sideways, 90° with leads flat against the board).
Find a good hiding spot. Wait. Enjoy.
