우선 사용 장치는 아두이노 메가와 3.5인치 TFT 컬러 LCD모듈(ICE-1825) 입니다.
 
아래 소스는 밑에 그림처럼 LCD에
----------------
ㅣ HELLO!  ㅣ
ㅣ1000      ㅣ
-----------------
 2줄의 영어와 숫자가 표시되어 느린 속도로 깜빡거리게 하는 것입니다.
 
문제는 여기서 '1000'을  '0'으로 바꾸어 '0'부터 시작해서 버튼을 누를 때마다 1씩 올라가도록 
 
버튼 값을 출력하려 하는데 버튼 값 출력하는 코딩은 아무리 찾아봐도 없어서..
 
혼자서 3일째 아무리 해도 안되고.. 계속 꼬여만가고.. 원인을 찾지 못해...
 
두번째 질문을 올립니다... ㅜㅜ
 
★★★ 제가 구현해보고 싶은것은 
 
버튼을 아날로그7 또는 디지털 31번에 연결해서 손으로 누를때마다 글자 옆의 숫자( "HELLO : 0")가
 
올라가는 것입니다.
 
제발 도와주세요ㅜㅜ
