Step 1: The Code

#include <Servo.h>

Servo myservo;

int switch1 = 6;

int switch2 = 4;

int switch3 = 9;

int switch4 = 8;

int speed1 = 1400;

int speed2 = 1370;

int speed3 = 1300;

int speed4 = 1600;

int speed5 = 1680;

int speed6 = 1800;

int stop = 1500;

float potVal;

float MaxDialVal;

float pwmVal;

float MaxpwmVal;

int nIts = 20;

int LowVolt = 227 + 180;

int HiVolt = 929 - 180;

void setup() {

myservo.attach(3);

pinMode(switch1, INPUT_PULLUP);

pinMode(switch2, INPUT_PULLUP);

pinMode(switch3, INPUT_PULLUP);

pinMode(switch4, INPUT_PULLUP);

Serial.begin(9600);

myservo.writeMicroseconds(1500); // send "stop" signal to ESC. Also necessary to arm the ESC.

}

void loop() {

int switch1value = digitalRead(switch1);

int switch2value = digitalRead(switch2);

int switch3value = digitalRead(switch3);

int switch4value = digitalRead(switch4);

if (switch1value == LOW && switch2value == LOW) {

myservo.write(stop);

Serial.println("Current Speed: Neutral");

}

else if (switch1value == LOW && switch2value == HIGH) {

if (switch3value == LOW && switch4value == HIGH) {

//

for (int i = 0; i < nIts; i++) {

    potVal = potVal;

}

potVal = potVal / nIts;

pwmVal = map(potVal, LowVolt, HiVolt, 1100, 2000); // maps potentiometer values to PWM value.

    MaxpwmVal = 1500 + (500 * (MaxDialVal / 1058));

//

myservo.writeMicroseconds(speed1);

Serial.println("Current Speed: Reverse 1");

}

else if (switch3value == LOW && switch4value == LOW) {

myservo.writeMicroseconds(speed2);

Serial.println("Current Speed: Reverse 2");

}

else if (switch3value == HIGH && switch4value == LOW) {

myservo.writeMicroseconds(speed3);

Serial.println("Current Speed: Reverse 3");

}

}

else if (switch1value == HIGH && switch2value == LOW) {

if (switch3value == LOW && switch4value == HIGH) {

myservo.writeMicroseconds(speed4);

Serial.println("Current Speed: Forward 1");

}

else if (switch3value == LOW && switch4value == LOW) {

myservo.writeMicroseconds(speed5);

Serial.println("Current Speed: Forward 2");

}

else if (switch3value == HIGH && switch4value == LOW) {

myservo.writeMicroseconds(speed6);

Serial.println("Current Speed: Forward 3");

}

}

}

Step 2: The Wiring

Check Joystick version for further info, the only difference is that the port A0 for the joystick will be replaced by inputs from a switch on D8 and D9.
