Replace one of the switches in 2-way switch by the SPDT latched relay controlled by arduinoAdd SPDT latched relay controlled by arduino to the existing 2-way switch ending up 3-way switch
Hello,I am having two way switches in my room. I am a newbie planning to do some home automation using Arduino and got a few questions in this directions.--> I am interested to keep the existing AC circuit intact. Would it be possible to add the arduino controlled output into the existing circuit making it a 3-way switch?Please do let me know of any other alternative approaches if the proposed approach doesn't work.The overall idea is to have my existing two way switches intact and add an additional switch thats controlled by Arduino enabling home automation.Any help is appreciated. Thanks.
