VOICE-ACTIVATED RELAY Model VAR1
https://www.bogen.com/sites/default/files/2021-01/var1_manual.pdf
The VAR1 Voice-Activated Relay is a DPDT relay device that is activated when an audio signal is detected at the microphone pre-amp or at 70V, 25V, or 600-ohm line level inputs. It has a number of useful applications, such as muting a sound system in response to a microphone or telephone page, activation of accessory (secu-

Step 3: Wiring (Relay Module) On the relay module, there are 3 pins. Negative pin connects to the ground pin on the Arduino. Positive pin connects to the 5v pin on the Arduino. S pin will be programmed to the 13th pin on the Arduino. Additionally, in order to test the relay switch, I will be using the 11th pin on the Arduino as a digital output.

Sound activated relay. The Sound Activated Relay can be used for turning on or off the lights in your house, for starting a voice recorder, for opening doors, activating sirens or other electric equipment with the sound of your voice, with a clap, a whistle or noise. The circuit is based on a R/S latch, built from NOR gates.

This audio frequency switched relay board will activate the onboard relay when the module detects the user-set input frequency from 2 KHz -15 KHz. The trigger frequency can be adjusted from 2 KHz -15 KHz using the onboard trimmer. The input voltage range is 100mV to 3V peak to peak. The circuit is based around an LM567C tone decoder IC.

Sound Activated Timer Switch Code. Since the Grove Sound Sensor produces a varying voltage, we can use the microcontroller’s analog-to-digital converter (ADC) to handle that voltage. So, here is a simple Seeeduino Sketch, also compatible with Arduino Uno/Nano, that reads the voltage from the sound sensor module connected to A0 which is then ...
