Start Arduino B'd & Sketch

 

 

 

win + x 를 눌러서 장치관리자를 열고 포트에 아두이노가 연결되어있는지 확인

나의 경우 USB serial port(com3) 가 아두이노 포트(사용자마다 이름이 다름)

아두이노 usb 포트 뒤에 적혀있는 com3 선택

 

Arduino Uno 선택

 

13번 포트 기준으로  LED 긴 다리, GND에 짧은 다리를 연결 후 upload(→ 표시) 하면 불빛이 깜빡인다.

 

 

오른쪽 상단에 Serial Monitor 클릭하면 콘솔창이 나온다.

 

 

 

1부터 100까지 출력 (반복)

 

 

 

3개 LED 불빛 켜기
