IoT Maker Lab: The Smart Home Sprint

A day-by-day plan we actually ship.

Students build six tiny IoT gadgets across six days — a motion-sensing night lamp, a plant-watering reminder, a Telegram-bot doorbell and more. Pure dopamine: every day they take a finished thing home. Uses ESP32 boards, free MQTT cloud and Blynk.
