Kids OK with adultESP32Level 2/3
Smart Medicine Box
At dose time the box beeps. A lid sensor confirms it was opened and the family gets a message.
Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
Power the clock module from 3V3, not 5V: its pull-ups would put 5V on the ESP32's I2C pins.
Strictly follow the description given with this video.

The video link will be added here soon.
How it works
- The DS3231 clock knows the exact dose times.
- At dose time the buzzer beeps.
- A magnet on the lid moves away from the reed switch when the box is opened.
- Opened = a 'taken' message; not opened in time = a 'missed' alert.
