Arduino ESC control with servo library

// ESC control using servo library
//
// ESC connector black wire -> Arduino GND
// ESC connector red wire -> Arduino 5V
// ESC connector white/yellow wire -> Arduino pin defined below

// Include servo library
#include <Servo.h>

// Define new instance of servo library
Servo ESC;

// Define pinout
const int ESC_PIN = 2;

// Define min. & max. HIGH-time (usually 1000us and
// 2000us, but some ESCs might work over a greater
// range so change as needed)
const int minOnTime = 1000;
const int maxOnTime = 2000;

// Create variable for rpm set point in % (may be
// changed at any time in your program to match your
// desired rpm)
float rpmPercentage = 100;

void setup()
{
  // Set ESC output pin
  ESC.attach(ESC_PIN);
}

void loop()
{
  // Calculate HIGH-time for given rpm
  int onTime = map(rpm, 0, 100, minOnTime, maxOnTime);

  // Set ESC signal
  ESC.writeMicroseconds(onTime);
