Sometimes having to get up and walk to the lights switch is too troublesome so we wanted to find a way to make it easier. My partner Nick and I came up with the idea of clap on/clap off lights.  Our design requires a loudness sensor, lights and, a Microbit. In order for the lights to turn on, there must be a sound larger than 1000 HZ which the the average sound of human claps. Furthermore, we are going to show “remember to clap to turn off lights” on LED.
