我需要运行我的BLDC电机。我偶然发现了这个代码，它可以让我通过按下键盘上的数字来移动我的BLDC电机。这个代码使我能够按下键盘编号并将电机设置为所需的转速。但我的马达似乎根本没有跑。请告诉我问题，也许是为什么我的BLDC电机不能运行的建议。
以下是代码：
// include the library code:
#include <LiquidCrystal.h>
#include <EEPROM.h>
#include <Keypad.h>
const byte ROWS = 5; //four rows
const byte COLS = 4; //four columns
//define the cymbols on the buttons of the keypads
char hexaKeys[ROWS][COLS] = {
{'1','2','3','A'},
{'4','5','6','B'},
{'7','8','9','C'},
{'*','0','#','D'},
{'*','0','#','D'}
};
byte rowPins[ROWS] = {2, 3, 4, 5};
byte colPins[COLS] = {6, 7, 8, 9};
//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad( makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS);
// initialize the library with the numbers of the interface pins

当您使用Arduino时，BLDC将无法使用analogWrite函数运行您必须使用servo.write(val)
BLSC的功能。
#include <Servo.h>
Servo myservo; // create servo object to control a servo
pos = 50;
void setup()
{
myservo.attach(9); // attaches the servo on D9 to the servo object
}
void loop()
{
// The min and max value is 0 and 180
//Change pos variable according to your requirement
myservo.write(pos);
delay(40);
}
