조건식에 오타도 있고 엉망이군요
조건식을 만들 때는 모든 스위치의 조건을 다 적어야합니다.
스위치 16가지 조건을 모두 체크해야 합니다.
조건식에 대한 결과가 맞지 않습니다.
반가산기 후 전가산기로 동작하려면
void loop() {// input a as two separate bitsbool a0 = digitalRead(A0Pin);bool a1 = digitalRead(A1Pin);// input b as two separate bitsbool b0 = digitalRead(B0Pin);bool b1 = digitalRead(B1Pin);// half adder for digit 0 of output sum and carrybool s0 = a0 ^ b0;bool c0 = a0 & b0;// full adder for digit 1 of output sum and carrybool s1 = (a1 ^ b1) ^ c0;bool c1 = (a1 & b1) | (c0 & (a1 ^ b1));digitalWrite(LED0Pin, s0);digitalWrite(LED1Pin, s1);digitalWrite(LED2Pin, c1); // digit2 of output will be carry from digit 1}링크글 제일 아래의 코드가 편하지 않나요?
