How to make Smart Clap Switch using Arduino | DIY Arduino Projects

The proper way to make a clap light switch is to use an Arduino or a microcontroller, because it allows the device not just to detect claps but to recognise a clap pattern, two claps in our case. Two clap pattern is much more reliable than a single clap because it prevents false triggering.
