Predictive Kettle Pre-Boil Scheduler Kit with Arduino Uno + Relay
Predictive Kettle Pre-Boil Scheduler Kit – Your Tea Starts Before You Do, with Arduino Uno & DS3231 RTC
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking into your kitchen to the sound of a just-boiled kettle, exactly when you need it—without ever pressing a switch. This advanced project kit builds a controller that learns your daily tea or coffee routine, then triggers a relay 3 minutes before your usual time so your water is ready instantly. By combining real‑time clock precision with pattern‑learning logic, you’ll create a truly intelligent home appliance that adapts as your schedule changes.
What You'll Build
A compact scheduler that monitors when you boil water, learns your recurring tea times, and pre‑activates your electric kettle ahead of each session. The device uses a DS3231 RTC for second‑accurate timing, a 0.96‑inch OLED to display the predicted schedule, and three tactile buttons for easy editing. After soldering everything on the included prototyping boards, you’ll have a permanent installation that makes every cup of tea feel magically timed.
What You'll Learn
- Interfacing a DS3231 real‑time clock with Arduino to capture reliable timestamps for pattern tracking.
- Writing an adaptive scheduling algorithm that records button‑press history and forecasts the next boil time.
- Controlling a mains‑voltage appliance safely using a 5V relay module with flyback diode protection.
- Designing a user interface on a small OLED display with tactile button navigation for schedule editing and override.

Who This Kit Is For
Engineering students—especially from ECE, EEE, and CSE streams at NIT, VIT, BITS Pilani, and affiliated colleges—building final‑year IoT projects or Smart India Hackathon demos will find a ready‑to‑demonstrate intelligent appliance. ATL tinkering labs and advanced makerspaces will appreciate the soldering‑intensive permanent build. Hobbyists who have already completed a few Arduino projects and want to tackle a practical smart‑home system will gain genuine embedded ML experience.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?

Do I need to modify my electric kettle?
No modifications to the kettle are required. The relay module interrupts the power cord externally—the kettle plugs into the controller, and you control the boil cycle safely without touching any internal wiring.
How does the scheduler learn my tea time?
Whenever you press the boil button, the Arduino logs the exact time from the DS3231 RTC. After a few days, the algorithm identifies your most frequent boiling windows and schedules a 3‑minute pre‑activation before that time automatically.
Can I override the automatic schedule and boil immediately?
Yes. The OLED menu, navigated with the tactile buttons, includes a “Boil Now” option that triggers the relay instantly, bypassing the predicted schedule whenever you need hot water outside your routine.
DS3231 RTC + learned schedule triggers relay 3 minutes before usual morning tea time. OLED editable schedule.
