I know this is more of an Arduino or Esp8266 (which is what I intend to use) issue. On the other hand, I don’t know if there are people who do this only with Arduino because it only makes sense with Blynk.
I want to make a volume control system for some speakers. I have 4 installed at home and I wanted to control their volume through Blynk. But I didn’t find any Arduino module that I can use for this. I want the receiver to send the signal to the module and the module to the speaker. Because I want to control it individually since I have situations where I need to turn down the volume on only one speaker and keep the others louder. Does anyone know any modules?
Not sure that would work on the output stage of an amplifier. It’s probably designed to be used on the input stage.
Even a fairly modest 10w per channel is quite a hefty load to control within a digital device. Take a look at the output transistors on a typical amplifier, and the heatsinks that they’re bolted to to get an idea of the power dissipation needed to handle the output stage power levels.
I think something like a home cinema controller with IR control would be the best way to go.
