Smart Pill Reminder with Arduino | LCD + Buzzer + Button | Tinkercad Simulation (No RTC)
Build your own DIY Smart Pill Reminder System using Arduino and Tinkercad – perfect for caregivers, the elderly, or anyone who needs help remembering medication times.
💊 What this video covers:
• How to simulate real-time pill reminders without a hardware RTC
• LCD shows the live clock using Arduino’s internal millis()
• System triggers buzzer and alert only within a chosen time window
• Pressing a button logs the dose and silences the alert
• Visual LED feedback for dose status
⏱ Dose times in this project:
• 08:00 (reminder active between 08:10–08:20)
• 14:00 (same logic)
• 20:00 (same logic)
You can customize easily to support more times per day.
✅ Entire project is simulated in Tinkercad — no external libraries required.
🎓 Great for students, hobbyists, and caregivers wanting to build smart medication tools!
📺 Next Episode (Part 2):
We’ll add a real DS3231 RTC using Wokwi + servo lock for timed access.
