Clap switch circuits are simple circuits mostly used to fashion sound signals as electrical control signals. Electronics clap switches are used in places where dynamic control of machines/devices is preferred such as a sound-activated light responding to a knock on the door. So, in this project, we are going to design a simple DIY Clap Switch Circuit Using a CD4017 Counter IC.
