Servo.h to run esc for brushed dc motor

Using Arduino Motors, Mechanics, Power and CNC
1

I am using the lesson below to control a brushed DC motor controlled by a bidirectional ESC for brushed motors.

I have set up the circuit the exact way it shows. The ESC powers up and the potentiometer values are output perfectly, but when I hook up the motor leads to my meter I get 0V so no motor spin.

The ESC has two options for signal input and I have tried both the single yellow input and your typical 3 wire servo signal plug

Can you give me advice? I'm guessing it's the signal type being sent to ESC from my UNO?

#include <Servo.h>

Servo ESC;     // create servo object to control the ESC

int potValue;  // value from the analog pin

void setup() {
  Serial.begin(115200);
  // Attach the ESC on pin 3
  ESC.attach(9,1000,2000); // (pin, min pulse width, max pulse width in microseconds) 
}

void loop() {
  potValue = analogRead(A0);   // reads the value of the potentiometer (value between 0 and 1023)
  potValue = map(potValue, 0, 1023, 0, 180);   // scale it to use it with the servo library (value between 0 and 180)
  Serial.println(potValue);
  ESC.write(potValue);    // Send the signal to the ESC
}
