arduino mega2560 ไฟdigital output ไม่พอครับ

arduino mega2560 ไฟdigital output ไม่พอครับ เช็คอุปกรณ์ดูแล้วปกติทุกอย่าง ครับ

อุปกรณ์ตามนี้ครับ

พอใส่โค๊ตัวนี้ไป

ไฟที่ขา 14 วัดได้ 0.22V. ครับ

แต่พอใส่โค๊ตตัวไนี้ไป

const int buttonPin = 9;     // the number of the pushbutton pin
const int ledPin =  14;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);
}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {
    // turn LED on:
    digitalWrite(ledPin, HIGH);
  }
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

วัดไฟที่ขา 14 ได้ 4.5-4.8 V.ครับ

โดยทั้งสองโค๊ตใส่อุปกรณ์เหมือนกัน

ช่วยแนะนำทีครับว่าอาการนี้จะแก้ไขยังไงครับ  ขอบคูณครับ
