Lorannoyatron
Lorannoyatron
This is a mashup of LoRa and an Annoyatron, producing a long range annoyatron.
The Lorannoyatron has two parts; a base station with an Arduino Pro Mini, DFPlayer, and SX1278 LoRa module,
and a remote control with a custom ATmega328PB board with another SX1278 LoRa module.
The remote control is used to select a sound to play and remotely trigger it on the base station.
Base Station
The base station is the speaker.
It needs a pretty good 5V power supply (at least 1A) or the DFPlayer will swamp it at high volume.
The base also has a useless 8 digit 7 segment display that shows random patterns.
The TEST button plays the recordings; the STOP button stops anything that's playing now.

The remote control is battery powered.
A knob selects a MP3 recording to play.
Another knob sets the volume.
The SEND button plays the selection on the base station.
