Arduino Audio Switch : 4 Steps - Instructables
https://www.instructables.com/Arduino-Audio-Switch/
Assembling of the switch box is very easy. Connect amp and speakers cables directly to relay or trought terminal block, as i have. Then relay module to Arduino as showed on schematic. Do not use Arduino VCC pin to drive 8ch relay. Connect relay module VCC directly to 5V and GND to common Arduino ground.
looking for audio switching relay - Audio - Arduino Forum
https://forum.arduino.cc/t/looking-for-audio-switching-relay/537074
So far, a Bluetooth audio library does not exist for the Arduino ESP32 core, so it will have to be done setting up and using an Espressif based toolchain. And that's what I struggle with at the moment. EDIT: I just found a project on the Internet where the ESP32 is used exactly to switch audio sources.
Voice Activated Relay Switch (Arduino) : 6 Steps (with ...
https://www.instructables.com/Voice-Activated-Relay-Switch-Arduino/
Inside the relay switch, there is a common contact that normally connects to the NC contact. Once the relay is energized, the common contact connects with the NO contact. Even if the common contact is connected using high voltage, the …
Solid-state relay boards: Can they be used to switch audio ...
https://arduino.stackexchange.com/questions/35473/solid-state-relay-boards-can-they-be-used-to-switch-audio-signals
1 A solid-state relay seems to be the totally wrong tool for the job. The image you posted shows it is intended to switch 240V AC. So it is designed to switch something like a 240V light on and off. Relays in general are things designed to connect one thing to another (eg. power to a light). They just aren't designed to switch audio signals.
Digital Pin as an on/off switch for Audio ... - Arduino Forum

Grumpy_Mike April 29, 2010, 9:17pm #9. You will find a transistor will not work as it is a current switching device. You need a FET or analogue switch. However you have to make sure that the audio signal is biased in the middle of the voltage range of the arduino or you will get half the wave chopped off.
MIDI Relay (switch) x8 and Audio loop x2 - Arduino Forum
https://forum.arduino.cc/t/midi-relay-switch-x8-and-audio-loop-x2/22633
I just ordered my 1st Arduino. I'm interested in prototyping a unit that would be capable of receiving MIDI program change messages and triggering 8 x relays and 2 x audio loops. Is this an typical/acceptable use of the Arduino? Thank you, Andy ... MIDI Relay (switch) x8 and Audio loop x2. Forum 2005-2010 (read only)
Arduino - Relay | Arduino Tutorial
https://arduinogetstarted.com/tutorials/arduino-relay
A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. It is used to programmatically control on/off the devices, which use the high voltage and/or high current. It is a bridge between Arduino and high voltage devices. WARNING
WiFi Controlled Audio Source Selector Switch (Wi-CASSS ...

The circuit consists of a Double Pole Double Throw (DPDT) Relay which switches the Left & Right Channel of the audio signals into two separate channels. Since relays are just an electromechanical switch, they don't distort the audio signals and most importantly, they are bi-directional. So audio signals can be given from any direction.
Driving A Relay With An Arduino - Arduino Project Hub
https://create.arduino.cc/projecthub/tarantula3/driving-a-relay-with-an-arduino-722c24
A relay accomplishes this by using the 5V outputted from an Arduino pin to energize the electromagnet which in turn closes an internal, physical switch to turn on or off a higher power circuit. The switching contacts of a relay are completely isolated from the coil, and hence from the Arduino. The only link is by the magnetic field.
