Smart Health Reminder Desk
You know that feeling when you sit down to work, blink, and suddenly it’s been five hours, your back hurts, and you haven’t had a sip of water? Yeah… me too. That’s why I’m making the Smart Health Reminder Desk!
It’s a small device that reminds you to drink water, take breaks, and stretch—because let’s be real, we all forget. Inspired by my own bad habits (and watching others do the same), I wanted a simple, non-annoying way to nudge people into healthier routines.
Think of it like a tiny, polite personal trainer for your desk—without the yelling. 💡
I got the idea from things like Pomodoro timers and hydration apps, but I wanted something physical—less screen time, more action!
Want a sneak peek? Imagine:
💡 Blinking LEDs telling you to hydrate or move.
🔊 A tiny buzzer (not too aggressive, I promise).
📟 A screen saying things like "Hey, stretch those legs!"
It’s basically a wellness coach that sits quietly on your desk—until it’s time to remind you! 😆

Fusion 360 is a powerful CAD tool used for 3D modeling, assembly, rendering, and animation. It’s widely used in manufacturing, machining, and industrial design—perfect for bringing ideas to life.
For this project, I followed a four-step workflow:
1) Sketching – Creating 2D outlines as the foundation of the design.
2) Extruding – Converting sketches into 3D components.
3) Assembly – Ensuring all parts fit together properly before fabrication.
4) Saving – Exporting files in the correct format for manufacturing.
With Fusion 360, I could refine and test the design before building, ensuring accuracy and efficiency!

System Overview:
The Smart Health Reminder Desk is an Arduino-based system that reminds users to take hydration and break intervals.
Input Components:
Hydration Button: Triggers the hydration reminder.
Break Button: Activates the break reminder.
Reset Button: Clears the screen and turns off LEDs.
Output Components:
16x2 LCD Screen: Displays messages like "Drink Water" and "Take a Break."
LED Indicators:
Power LED (always on) ensures the system is active.
Hydration LED (blinks when active) reminds the user to drink water.
Break LED (blinks when active) signals a break reminder.
Integration & Functionality:
When a button is pressed, the Arduino reads the input and updates the LCD.
The corresponding LED blinks to reinforce the reminder.
Pressing the reset button restores the default screen and turns off active LEDs.
Tools & Components Used:
Hardware: Arduino Uno, 16x2 LCD with I2C (0x27), three push buttons, three LEDs.
Software: Arduino IDE, Wire.h and LiquidCrystal_I2C.h libraries.
Power Source:
The system operates via USB or an external 9V adapter.

Challenge 1:
Issue: LCD Display Not Showing Text Properly
Initially, when powering the circuit using an adapter instead of a USB connection, the LCD sometimes failed to display text. This was likely due to power stabilization issues when switching power sources.
Solution:
Introduced a small delay (delay(500);) in setup() after turning on the power LED.
This ensured that the LCD had enough time to initialize properly before displaying text.
As a result, the text on the LCD now appears consistently regardless of the power source.
_____________________________________________
Challenge 2
Arduino didn't provide (5V) for the LCD, instead it provided 3.5 V everytime I connect the 9V adaptor.
Solution:
I consulted the instructor and it turned out to be a fault in the Arduino voltage regulation circuit.
Trial 1:
I put a voltage regulator.
Result: It burnt 🤣
Trial 2:
I changed the curcit to be based on 5V power source instead of 9V
Then I changed resistors and chose lesser values (320 OHM) to make sure LEDs light properly.
Result: Everything workedcorrectly.
