Updated New

• 하나의 칩으로 구성된 작은 컴퓨터 • processor, memory, input/output

• 주로 Embedded 영역에서도 최저 성능/비용

• Arduino, Raspberry Pi…………

• Typical components include: • power circuit • programming interface • basic input; usually buttons and LEDs • I/O pins

• 첫 번째 샘플 LED 점멸

• File > Examples > Digital > Blink

• 13번 Pin과 GND를 연결한다.

www.instructables.com

pinMode(pin, mode) Sets pin to either INPUT or OUTPUT

digitalRead(pin) Reads HIGH or LOW from a pin

digitalWrite(pin, value) Writes HIGH or LOW to a pin

delay(ms)

–Pauses for a few milliseconds

delayMicroseconds(us)

–Pauses for a few microseconds

setup( ) : 최기화에 필요한 내용들을 기술한다. loop( ) : main( )함수에 해당하는 곳이지만 지속적으로 반복하는 점이 차이

• Digital has two values: on and off

• Analog has many (infinite) values

• Computers don’t really do analog, they quantize

• Remember the 6 analog input pins---here’s how they work

SoftwareSerial : Bluetooth 모듈 시리얼 포트를 지정한다. BTSerial.begin( ): 통신을 시작한다. BTSerial.write( ) : 문자를 전송한다. BTSerial.read( ) : 문자를 수신한다.
