1. Download the latest release from GitHub Releases
2. In Arduino IDE: Sketch → Include Library → Add .ZIP Library
3. Select the downloaded RCduino.zip file
4. Restart Arduino IDE

Add to your platformio.ini:

lib_deps = 
    RCduino@^2.0.0

#include <RCduino.h>

RCduino myVehicle(RC_CAR);

void setup() {
  // Add H-Bridge motor (IN1=9, IN2=10)
  myVehicle.addMotor(9, 10, BRUSHED_DC);
  
  // Add steering servo
  myVehicle.addServo(6);
  
  // Add receiver
  myVehicle.addReceiver(PWM_SIGNAL);
  myVehicle.getReceiver()->addChannel(0, 2);  // Throttle
  myVehicle.getReceiver()->addChannel(1, 3);  // Steering
  
  // Add battery monitor
  myVehicle.addBattery(A0, 11.0);  // 11:1 voltage divider
  
  // Add IMU (optional)
  myVehicle.addIMU();
  
  myVehicle.begin();
  
  // Calibrate IMU
  myVehicle.calibrateIMU();
}

void loop() {
  myVehicle.update();  // Handles everything automatically
}

• ESC: Any standard brushless ESC (1000-2000µs PWM)
• H-Bridge: L298N, TB6612FNG, DRV8833, or similar

• IMU: MPU6050 (I2C address 0x68)
• GPS: NEO-6M, NEO-7M, or any NMEA-compatible GPS module
