ESP8266 Community Forum

- Sat May 22, 2021 9:47 pm #91455 I am trying to control a brushless motor with WeMOS D1 ESP8266

The motor controller and motor specs are below:

A 11.1v LiPo battery powers both the controller and ESP8266 (VIN, GND, D9)

The motor controller user manual is here:

The wiring photo is here

Turning on the controller spins its fan. but the motor does not spin.
What is the arming procedure to get the beeps to get the motor started?


Here' some code:

Code: Select all#include <Servo.h>

Servo ESC1;

int pos = 0; //Sets position variable

void arm(){
  setSpeed(0); //Sets speed variable
  delay(1000);
  setSpeed(90); //Sets speed variable
  delay(1000);
  setSpeed(135); //Sets speed variable
  delay(1000);
  setSpeed(0); //Sets speed variable
  delay(1000);
}

void setSpeed(int speed){
  int angle = map(speed, 0, 100, 0, 180); //Sets servo positions to different speeds
  ESC1.write(speed); //angle
}

void setup() {
  ESC1.attach(2); //Adds ESC to certain pin.  GPIO2 is pin 9
  arm();
}

void loop() {

  int speed; //Implements speed variable

  for(speed = 0; speed <= 70; speed += 5) { //Cycles speed up to 70% power for 1 second
    setSpeed(speed); //Creates variable for speed to be used in in for loop
    delay(1000);
  }

  delay(4000); //Stays on for 4 seconds
 
  for(speed = 70; speed > 0; speed -= 5) { // Cycles speed down to 0% power for 1 second
      setSpeed(speed); delay(1000);
  }

  setSpeed(0); //Sets speed variable to zero no matter what
  delay(1000); //Turns off for 1 second

}
