  Components Required ESP32 Development Board 2 × LEDs (any color) 2 × 220Ω resistors Breadboard & jumper wires USB cable for programming ESP32 Circuit Connection : Connect LED1 anode (long leg) → 220ohm resistor → GPIO16. Connect LED2 anode (long leg) → 220ohm resistor → GPIO17. Both LED cathodes (short leg) → GND. Step 1: Install Arduino IDE & ESP32 Board Download and install the Arduino IDE from Arduino.cc . Add ESP32 board support: Go to File > Preferences. In Additional Board Manager URLs, add: https://dl.espressif.com/dl/package_esp32_index.json Go to Tools > Board > Board Manager, search ESP32, and install. Step 2: Connect ESP32 and Select Board Plug ESP32 into your computer with USB cable. In Arduino IDE: Go to Tools > Board → Select ESP32 Dev Module. Select the correct Port. Step 3: Full Arduino Code #include <WiFi.h> // Replace with your network credentials const char* ssid = "YOUR_WIFI_SSID"; const char* password = "YOUR_WIFI_PASSWORD...

  Controlling Servo With MPU6050 Gyro Sensor Using ESP32 - Servo Control Using ESP32 MPU6050 measures accelerometer + gyroscope. Code calculates pitch from accelerometer (X tilt). The pitch (range -90° to +90°) is mapped to servo angles (0°–180°). The servo on GPIO 13 moves according to tilt. 📌 Wiring:- MPU6050 → ESP32 VCC → 3.3V GND → GND SDA → GPIO 21 (default I²C SDA on ESP32) SCL → GPIO 22 (default I²C SCL on ESP32) Servo → ESP32 Signal (orange/yellow) → GPIO 13 VCC (red) → 5V (use external supply if possible, not directly from ESP32) GND (black/brown) → GND (common ground with ESP32 & MPU6050) ⚠️ Important: Servos draw a lot of current → use an external 5V supply for the servo, not just the ESP32’s 5V pin.
