Hi, I need some cheap way to turn on the ac socket with arduino. I just need to have a way to turn on or off 2 devices with relatively low consumption (2 satellite receivers) remotely (I already receive the switch signal to the Arduino) I thought to do it using a dc motor and a classic switch ac socket, but this solution is quite ugly. if you had a solution (I’m not an electrician and I wouldn’t like to interfere with 230v ac) I would definitely welcome it. Please let it be cheap as possible because it’s nothing so important and I don’t have the money to waste.
that’s done with a relay
Another approach is getting some remote-controlled mains adapters that have been
interfaced to by one of the various libraries for this - try starting here perhaps: https://www.instructables.com/Using-433MHz-Remote-Controlled-Switches-on-Arduino/
Look into using a solid state relay, SSR, for your project. 5 volts from an Arduino pin turns on the AC power. 0 volts from the pin turns off the power. I have one and a Nano controlling the irrigation water from my well and it performs flawlessly for 3 years.
