Noise traffic light (semaforo de ruido)

thingiverse

Here is the rewritten text: This device features a microphone and a traffic light that changes color in response to the ambient noise level, while also emitting a buzzing sound when it reaches red. It comes with a display screen for selecting one of five pre-programmed volume levels at which the alarm sounds and the light changes color. Additionally, it has a counter to track how many times the light has reached red. It is designed to control noise levels in kindergarten classrooms and first-grade primary school classes.
