Marcelo Dalvali built a smart crib mobile that detects a crying baby and plays a lullaby while spinning a toy. The sound sensor triggers at around 500 decibels, activating a piezo speaker and motor, but the current motor doesn't have enough torque to reliably spin the wheel with toys attached.

Questions this video answers

Approximately 500.

Sound sensor, piezo speaker/buzzer, and a motor.

The toy motor lacked sufficient high-torque/low-speed capability to spin the wheel with toys attached.

Hi, my name is Marcelo.
Dalvali. I'm presenting my final project. It's a smart baby mobile. And the idea behind is that I just got a baby two weeks ago and this hopefully will help me take care of the baby when he cries. Major components, a sound sensor, a piezo speaker, a buzzer, pretty much. And you have a motor. And the idea is that if the baby cries in the middle of the night, you would activate the Sensor. There's a 500 threshold and if it goes past that, it will activate the sound sensor and you will get the music to play the lullaby and the wheel to sp. It just worked before. Okay, great. Fantastic. Maybe angry baby. I'm okay with that because my baby cries a lot louder than this. He's really, really strong. The issue I had was with my motor that I didn't get the high torque, low speed motoring time. I'm using a toy mot, so it doesn't have enough torque to spin the wheel with all the toys in there. And if I try to speed it up too high, it spins too fast and it breaks. So at this point I can't really present that. But once I have the right motor in there, it should work fine. The code and all the parts are working together perfectly.
