Room-based automation system

Playing around with the intersection of Blynk API and hardware.

Won at PBL Expo 2024

Overview

Networked home automation prototype controlling appliances via Blynk API and microcontrollers. Demonstrates multi-sense environment control: visual (WS2812 LED patterns), auditory (mood-countering playlists), and olfactory (custom fragrance pump). Engineering pivoted from MTCNN/YOLOv8 to Haar Cascade for real-time performance.

Features

WS2812 LED visual moods
Mood-based playlists
Custom fragrance actuation
Haar Cascade for low-latency

Tech Stack

Arduino: Microcontroller IDE
WS2812: RGB LEDs Ring strip
Blynk: Application for IoT control
Embedded C: For hardware programming
