BabyMonitor, is a prototype of a sensor that detects when the baby is crying, and automatically alerts the parents via a phone call, and starts playing lullaby with a simple light touch to soothe the baby.
The current version is a working prototype, which showcases the main ideas. The main design goal is not re-inventing Baby Monitor, but to illustrate how to build the sensor using Arduino.
/Docscontains the Arduino circuit diagram and the final prototype./babyMonitorcontains the Arduino sketch.
- Arduino UNO
- Breadboard
- Jumper Wires
- Sound Detector
- Arduino GSM Shield
- Piezo Buzzer
- 2x LED
- 2x 560Ω Resistor
- Box or children's toy
- Attach the GSM Shield to Arduino UNO.
- Connect the Sound Detector red cable (+) in Arduino digital pin #5 and black cable (-) into ground pin.
- Connect the Piezo Buzzer red cable (+) in Arduino digital pin #8 and black cable (-) into ground pin.
- Connect the Sound Detector (+) in Arduino digital 3.5V and black cable (-) into ground pin, and Pin A0 to pin #5.
- Connect and Set the LEDs in pin #12 and #11 to light-up.
- "Twinkle Twinkle Little Star" is the melody that have been used in this project, you can costumize your own melody by going through this tutorial.
- Put the sensor inside a box or a children's toy.
The full schematic of our completed prototype will look like the following:
