Predictive Kettle Pre-Boil Scheduler Variant 5 Kit with Arduino Uno + Relay
Predictive Kettle Pre‑Boil Scheduler Kit V5 – Arduino Uno + Relay for Morning Tea Automation
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 as the kettle reaches a perfect boil for your morning tea — without ever touching a switch. This kit goes beyond a simple timer: it learns your weekday and weekend usage patterns, then fires the relay three minutes early so hot water is ready exactly when you are. Designed and tested for India’s 230V AC kettles, it’s an intelligent companion that elevates a daily ritual into a frictionless smart-home experience.
What You’ll Build
A standalone predictive kettle scheduler that mounts near your kettle, reads the time from a DS3231 RTC, and automatically switches a 5V relay to turn on your kettle 3 minutes before your usual tea time. An OLED display, navigated by three tactile buttons, lets you view and edit the learned schedule — no phone or cloud connection required. The unit remembers separate weekday and weekend timings, and the predictive algorithm adapts as your routine changes.
What You’ll Learn
- Integrate a high-precision DS3231 real-time clock with an Arduino Uno for sub-second timekeeping
- Program a non‑intrusive machine learning routine that observes and adapts to daily kettle usage patterns
- Drive a 0.96‑inch OLED display and build a three‑button menu for editing schedules and viewing system status
- Safely control a mains‑powered appliance through a relay module with flyback diode protection and optocoupler isolation

Who This Kit Is For
Engineering undergraduates in B.Tech ECE or EEE at IITs, NITs, VIT, or BITS Pilani building a home automation mini‑project. Diploma students prototyping for the Smart India Hackathon who need a reliable, mains‑rated appliance controller. Advanced hobbyists who have completed intermediate Arduino builds and want to embed real‑world machine learning into a daily kitchen appliance.
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?
Our AI build companion, accessed via the QR code on the box, walks you through every wiring step and code upload. For tricky debug moments, WhatsApp our support team for a prompt guided fix.
Can I edit the schedule after the initial learning?
Yes. The OLED menu and three buttons let you increase or decrease the trigger time in 5‑minute increments. The AI companion explains how to reset the learned pattern if your routine changes permanently.
What safety measures are included for the relay switching?
The relay module is optocoupler‑isolated for 230V AC safety. The kit includes a 1N4007 flyback diode across the relay coil and a 10kΩ pull‑down on the transistor base to prevent false triggering or voltage spikes.
Does this kit work with any electric kettle?
It is designed for standard Indian 230V AC kettles up to 10A. Most household kettles with a mechanical on/off switch that can be left in the “on” position are compatible. Always verify your kettle’s current rating does not exceed the relay’s 10A limit.
DS3231 RTC + learned schedule triggers relay 3 minutes before usual morning tea time. OLED editable schedule.
