동작 내용에 대한 설명 : 좌측에 위치한 가변저항기로 선책한 0~1023사이의 숫자를 오른쪽 가변저항기로 맞추는 게임이다. 오른쪽 가변저항기로 값을 추측한 값을 입력하고 우측하단의 버튼을 누르면 정답인지 오답인지 알려준다. 오답인 경우 LCD에 표시된 시도횟수를 1만큼 상승하고 입력한 값이 정답과 비교해서 큰지 작은지 LCD에 표시한다. 정답인 경우 총 시도 횟수를 표시하고 게임을 종료한다.

동작 내용에 대한 설명 : 주어진 십진수 숫자를 2진수로 변환하는 게임이다. 슬라이드 스위치를 끄고 켜는 것으로 1과 0을 표현할 수 있다. 원하는 2진수를 표현했다면 tact 스위치를 눌러서 정답인지 확인한다.
