Can anyone tell me how I might go about wiring this relay directly to the photon?
Would it be something like D0 in and GND out? I’m thinking about using it for an alexa controlled extension cord, unless anyone has any better suggestions on the hardware (UK 240V 13A rated).
Also, should I use a transistor of some kind to control the IO rather than running it straight from the D pin? If so, how and what kind would be best?
