How to run four brushless motor using Arduino simultaneously

Copy the code below.

#include <Servo.h> Servo m1; Servo m2; Servo m3; Servo m4; void setup() { m1.attach(5); m2.attach(6); m3.attach(9); m4.attach(10); m1.write(180); delay(2000); m1.write(0); delay(2000); m2.write(180); delay(2000); m2.write(0); delay(2000); m3.write(180); delay(2000); m3.write(0); delay(2000); m4.write(180); delay(2000); m4.write(0); delay(2000); } void loop() { m1.write(10); m2.write(10); m3.write(10); m4.write(10); }
