르누아르는 이전부터 제가 좋아했던 인상주의 화가입니다. 그가 묘사한 세계에,
아마도 그의 시각에 의해 재해석된 세계관에 제가 직접 들어갈 수 있다면 어떨까하는
생각에 만들어본 작품입니다. 액자를 정자세로 놓으면 상태가 꿈이되어, 그의 세계로
들어갈 수 있습니다. 다시 뒤집어 놓으면, 현실로 돌아오게됩니다.
사용된 재료 : MPU6050, ArduinoR3, 브레드보드와 전선
사용된 프로그램 : Arduino, VVVV
구현 설명 : 아두이노와 vvvv를 vvvv의 비공식패치인 RS232패치를 이용하여 통신합니다.
프로세싱이나 Max 와의 시리얼 통신과는 방식이 조금 다른데요, vvvv와 통신 할 때에는
Serial Write 로 채널을 맞춰준뒤, Serial Print 로 시리얼 값을 string(문자)으로 보내게 됩니다.
아두이노의 시리얼 값을 RS232는 string (문자) 값으로 받아, vvvv에서 이를 다시 numerical
(숫자) 값으로 바꾸어 주어야합니다. 그리고 그 값을 map으로 조정해 그림 배경의 스케일값에
연결하였습니다.
아두이노 코드
