You need to keep unwanted guests out of your office or bedroom you may be interested in a new Raspberry Pi digital do not disturb sign project published to the official Raspberry Pi magazine website this week. Offering an easy to build project using the Raspberry Pi Zero W mini PC together with a Scroll pHAT HD and small mechanical switch equipped keypad.
“In this tutorial we’re going to use a popular messaging protocol, MQTT (Message Queuing Telemetry Transport). With MQTT we will set up a simple do-not-disturb sign that you can trigger with a single key press and customise to your heart’s content. We’re using two Raspberry Pi Zero W computers for this project, although it will work with any recent model. For both, we recommend installing Raspberry Pi OS Lite (magpi.cc/software) as we don’t need a desktop interface. Make sure both devices are working and connected to the same network. We also recommend setting their host names by running sudo raspi-config at the command line, then going to System Options > Hostname. We chose ‘busybot’ for the sign and ‘buttonbot’ for the controller and that’s how we’ll refer to them throughout this tutorial.”
