Serial Monitor ไม่แสดงผล
ตามหัวข้อเลยค่ะ ไม่ยอมแสดงผลให้ค่ะ
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.println ();
Serial.println ("Hello world");
}
ส่วนอันนี้ Code ค่ะ
โคดที่ให้มาทำงานได้ถูกต้อง แสดงผลได้ครับ
เช็คดังนี้
1. เลือก บอร์ด และ Comport ถุกต้องแล้ว
2. เลือก boardrate ให้ถูกต้อง ในโปรแกรมตั้งเป็น 9600 ใน Serial Monitor ก็ต้องตั้งให้ตรงกันด้วยครับ
