ESP32 + OpenCV Hand Control (4-Channel Relay) — Turn Anything ON with Hand Gestures!

Learn to CONTROL real devices with just your HAND — ESP32 + 4-Channel Relay + OpenCV (Full setup, VS Code, Python installs, WebSocket demo & troubleshooting). Watch & follow step-by-step — everything works in under 15 minutes. ⚡️🤚🔌 ESP32 + OpenCV Hand Control (4-Channel Relay) — Turn Anything ON with Hand Gestures! 📎 DOWNLOAD :https://drive.google.com/drive/folder... 🔥 WHY WATCH THIS (FAST): This video shows exactly how I wired an ESP32 to a 4-channel relay, installed VS Code toolchain, set up Python + OpenCV (MediaPipe), and sent WebSocket commands from your PC to toggle AC devices with hand gestures. Perfect for makers, students, and anyone who wants a fast, safe IoT demo that actually works — with all fixes for the common errors you’ll hit. 🔑 KEYWORDS (what this video ranks for): ESP32, relay module, 4-channel relay, OpenCV, MediaPipe, hand gesture control, WebSocket ESP32, VS Code ESP32, Python OpenCV tutorial, home automation. 📌 WATCH OR SKIP — TIMESTAMPS 00:00 Intro & project overview (what it does) 00:30 Parts list & quick safety notes (read this before wiring!) 01:10 Wiring: ESP32 → 4-channel relay (close-up) 03:05 Powering the relay board (5V / JD-VCC vs VCC explained) 04:30 VS Code & ESP32 toolchain setup (extension + upload) 06:00 Upload ESP32 sketch + Serial Monitor (find IP) 07:10 Python environment & pip installs (copy/paste commands) 08:10 OpenCV + MediaPipe gesture detection explained 09:20 WebSocket client → send commands (S1_ON / S1_OFF) 10:30 Live demo: hand gesture toggles relay (real demo) 11:30 Troubleshooting: relays not clicking, no WiFi, 3.3V logic issues 13:00 Final tips, safety wrap-up & download links 🧰 PARTS I USED ESP32 dev board (any common ESP32 devkit) 4-Channel Relay Module (SRD-05VDC-SL-C) — use JD-VCC isolation if available 5V power supply for relay module (or USB power bank for demo) Lamp / low-voltage demo load (use a safe lamp or test load; don’t show exposed mains on camera) ⚠️ SAFETY FIRST — READ THIS BEFORE YOU WIRE OR SWITCH MAINS If you’re switching mains/AC: only switch the LIVE (hot) conductor, not neutral + earth. Use insulated connectors and an enclosure. Do not film exposed live wiring. If you’re unsure about mains wiring, get help from a qualified electrician. For safe demos, use a low-voltage lamp or a simulated load (better for YouTube). 💻 COPY / PASTE: SETUP COMMANDS (Windows & Linux/Mac) Windows python -m venv env .\env\Scripts\activate pip install --upgrade pip pip install opencv-python mediapipe websocket-client numpy 🧩 QUICK PROTOCOL NOTES (how PC talks to ESP) ESP32 runs a WebSocket server on port 81. Commands: S1_ON, S1_OFF, S2_ON, S2_OFF, ... (text messages). Relay logic: active-LOW on the module used in this video — LOW = relay ON, HIGH = relay OFF. Confirm with your board. 🐞 TROUBLESHOOTING — QUICK FIXES (most common problems) Relay doesn't click → check relay VCC (5V) & common GND with ESP32. Relay coils need 5V; IN pins are logic inputs. Relays trigger randomly → module may require pull-ups or an opto/isolation; use JD-VCC and isolate ESP ground if needed. WebSocket can’t connect → confirm ESP32 IP from Serial Monitor and port 81. Ping from PC first. Gesture jitter / toggles too fast → add a hold time or debounce: require gesture to be held for 0.5–1s before sending. Noisy detection at corners → smooth landmark coordinates (moving average) and check lighting. 📎 DOWNLOAD (copy to your repo / Google Drive): ESP32 sketch: https://YOUR_LINK/ESP32_sketch.ino OpenCV Python script: https://YOUR_LINK/opencv_hand_relay.py (Replace with your GitHub or Drive download links before uploading the video.) --Stuck on an error?
