    It's an "optocoupler" relay module operating at 12 Volt. Does this mean that 12 V is galvanic isolated from the arduino, that should control the relays? My first impression was: I am missing a separate ground for the relay control and for the arduino! However, after some study I discovered that you CAN operate the board with galvanic isolated 12 V and the arduino's 5 V. How? Don't use the straps!! So don't connect the 4 middle pins with straps to Ground or to VCC of the relay module, but connect these

I could have bought and fitted the commercial "lights" module into the caravan but they are

    Items arrived. Order a mixture of electronics components, and heavy gear motors - packaging insufficient to protect electronics from heavy motors....
