RGB LED Strip Control System – Special Project Guide

🌟 PROJECT OVERVIEW
This document outlines an ESP32-based RGB LED control system with the following features:

  • 2-channel PWM control (for red and green LED strips)

  • Automatic relay control after 7:00 PM (based on Turkey/Istanbul time)

  • Web interface and physical button control

  • HC-SR04-based presence detection for energy saving

  • LED dance mode based on Ankara weather data

🛠️ HARDWARE DETAILS

🔧 Required Components:

  • ESP32 DevKit v1 (1 unit)

  • IRFZ44N MOSFET (2 units - for red and green LED strips)

  • 5V Relay Module (1 unit - room light control)

  • HC-SR04 (1 unit - distance measurement)

  • 128x64 OLED (I2C) (GPIO6 SDA, GPIO7 SCL)

  • 10K Potentiometer (2 units - GPIO4 and GPIO5)

  • Push Button (3 units - GPIO8, GPIO9, GPIO10)

  • 10K Resistor (5 units - for pull-up)

  • Breadboard (1 unit)

  • Jumper Wires (20+ units)

🎛️ Pin Mapping:

🔄 Flashing Process (Arduino IDE):

  • Tools > Board > ESP32 Dev Module

  • Flash Mode: "QIO"

  • Flash Size: "4MB (32Mb)"

  • Partition Scheme: "Default 4MB"

Custom Settings:

#define WIFI_SSID "YourSSID" #define WIFI_PASS "YourPassword" #define OWM_API_KEY "YourAPIKey"

🎛️ SYSTEM FEATURES

💡 LED Control System:

PWM Features:

  • 8-bit resolution (0–255)

  • 5kHz PWM frequency

Control:

  • POT1: Red LED intensity

  • POT2: Green LED intensity

⏱️ Time-Based System:

  • Timezone: Turkey/Istanbul (GMT+3)

  • Relay activation based on HC-SR04 after 7:00 PM:

    • Person detected: ON

    • No presence: OFF

🌤️ Weather Integration:

  • Ankara weather (OpenWeatherMap API):
    GET https://api.openweathermap.org/data/2.5/weather?q=Ankara,TR&appid=YOUR_API_KEY&units=metric&lang=en

  • BTN3 (double click): Activates dance mode — LEDs synchronize based on weather

🖥️ USER INTERFACE

🔧 TROUBLESHOOTING GUIDE

🚨 Common Issues:

LEDs Not Working:

  • Check MOSFET gate resistor (10K–100Ω)

  • Verify 12V power supply

  • Lower PWM frequency (try 500Hz)

HC-SR04 Inaccurate Readings:

#define TRIG_PULSE 10 // 10μs trigger pulse #define MAX_DISTANCE 400 // Max 4 meters

WiFi Connection Problems:

WiFi.mode(WIFI_STA); WiFi.begin(ssid, password, 6); // Use channel 6

📊 Serial Monitor Test Commands:
