Arduino UNO 전원 연결

전원 아두이노 우노는 USB나 외부전원을 이용하여 전원을 공급할 수 있으며, 전원소스는 자동으로 선택됩니다. 외부전원은 DC어댑터나 배터리를 사용할 수 있습니다. 사용가능한 어댑터는 중심이 양극인 플러그이며 지금이 2.1mm이여야 합니다. 배터리의 경우 전원커넥터의 Gnd와 Vin핀에 배터리의 음극와 양극을 연결하여야 합니다. 추천 사용전압은 7V~12V입니다. 보드는 외부전원 6V~20V를 사용할 수 있지만, 7V미만의 전압을 공급할 경우 5V핀이 5V이하로 내려갈 수 있어… Read More »
