So i want to shrink the project and make it work with just one plug for both, arduino and the lamp, but i am a bit scared working with 220v with my limited knowledge of electronics. This tutorial also explains how does a relay works. A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet which in turn closes an internal, physical switch to. To develop a program which will subscribe to mqtt broker and fetch the latest message available and accordingly switch the 5v relay. First of all we note that this type of relay operates at 12v coil 12v while the outputs of arduino are to 5v. You can use a 5v relay to switch the 120240v current and use the. Nov 17, 2019 watch the video to find out what they did wrong and how a small arduino eg nano or even an attiney85 comes to the rescue. Since the arduino operates at 5v it cant control these higher voltage devices directly, but you can use a 5v relay to switch the 120240v current and use the arduino to control the relay.
