🎙 muteme

Wireless button that toggles mute on and off. Built on Puck.js.

Load the button

1. Open the Espruino Web IDE and connect to your Puck.js over Bluetooth.
2. Paste code.js into the editor and use Send to Espruino to upload it.

Button behavior

The Puck.js acts as a Bluetooth keyboard named Mute Button:

• Pressing the button sends Ctrl+Alt+M to toggle microphone mute through a matching hotkey on the computer.
• On connect, it sends Ctrl+Alt+X, intended to mute, and assumes a muted state. Neither included workflow binds this shortcut.
• Green means the button considers the microphone unmuted; red means muted. This tracks the button's own state, without reading the computer's microphone state. Each LED indication times out after 10 minutes; disconnecting clears both LEDs.

Alfred workflows

The included workflows control macOS microphone input volume:

• Mic-PTT-Hotkey.alfredworkflow binds Ctrl+Alt+M to toggle input volume between 0 (muted) and 80 (unmuted). It shows a notification. Despite the PTT name, it toggles rather than requiring a held button.
• Mic-Unmute-Hotkey.alfredworkflow binds Ctrl+Alt+A to set input volume to 80 (unmuted), with a notification.
