Arduino project that turns lamp on and off with clapping.
This project uses high voltage. Do NOT attempt to build this project unless you know what you are doing. And do NOT even attempt to build one if you have heart problems or weak heart or wearing a pacemaker, because one little shock from relay can be fatal. Never ever touch cables or relay before you unplug the cable from the power source and use properly casing for all parts. I am not responsible for any injuries or deaths caused by this this example project.
