can you not add 4 switches also to these for local control , as you did in the 1 Relay project

I just want to know if I can connect a mic to it and have a two way bluetooth radio. Actually I have a HAM gear and I want to connect it to Spk/Mic and be able to Rx and Tx audio from it

it does not work, still give the same error any help

Is the arduino really required. Why can't it be on the ESP itself.

I guess, building the Gas sensor with a small opamp with adjustable logic output and interfacing it with the ESP8266 port pin would have been a better idea. In which case you could have simply eliminated the Arduino and made the project simple and attractive. Anyway, just my thought and idea.

I am also planning to try it, not yet tried it, Actually my CC2500 projects use the scheme. I was just wondering why are people not using the same. Thank you for the confidence
