My project is called the Health Band. It is a simple but useful wearable device designed to remind people to stay healthy by drinking water and taking rest at the right time. The band gives hourly reminders through both a buzzer and an LCD display. The screen shows helpful messages like “Drink Water,” while the buzzer chirps for 60 seconds. If someone wants to stop the sound, they can press the push button, which immediately turns off the buzzer.

To build this project, I used an LCD display, a push button, a buzzer, MicroPython, and other input–output pins connected through my microcontroller. In the code, I began by importing the necessary modules such as Pin, PWM, and sleep. Then I initialized the LCD pins and declared variables needed for the program. I also set up a counter to keep track of how many times the button is pressed.

The buzzer tone and its duration were defined in a separate function. The main logic runs in a while True loop, where the LCD repeatedly prints “Drink Water.” During each cycle, the code checks if the button value is 1. If the button is pressed, the program prints “Button Pressed” for debugging, stops the buzzer, clears the LCD, and resets the counter. If the button is not pressed, the buzzer rings for a set duration, and the LCD continues displaying the reminder.

If the buzzer completes 60 seconds without interruption, the system goes to sleep for 3,600 seconds—exactly one hour—before reminding again. This project helped me understand how loops, timers, and input detection work in MicroPython. It was fun building something useful that can help people stay healthy.
