这是我第一次使用 Arduino Due（或任何 Arduino）。所以昨晚我正在使用我的 Arduino Due，它工作正常。但是当我今天使用它时，它不起作用，所以我尝试检查串行监视器的输出，我看到它产生“ÿ ÿ”额外！
这是我的 Arduino 代码：
//enter code here
int lock = 6; //pin 6 on Arduino
int unlock = 7;
int lock2 = 8;
int unlock2 = 9;
int lock3 = 10;
int unlock3 = 11;
char final[4]; //Characters the Arduino will receive
char correct[4] = {'A','A','A','A'}; //User-Defined Password
char correct2[4] = {'B','B','B','B'};
char correct3[4] = {'C','C','C','C'};
int pass_correct = 0; //Does Password match, 0=false 1=true
void setup()
{
pinMode(lock, OUTPUT);
pinMode(lock2, OUTPUT);
pinMode(lock3, OUTPUT);
pinMode(unlock, OUTPUT);
pinMode(unlock2, OUTPUT);
pinMode(unlock3, OUTPUT);
Serial.begin(38400);
Serial2.begin(19200);
Serial3.begin(115200);
digitalWrite(lock, HIGH); //By default, lock is active(locked)
digitalWrite(lock2, HIGH);
digitalWrite(lock3, HIGH);
digitalWrite(unlock, LOW);
digitalWrite(unlock2, LOW);
digitalWrite(unlock3, LOW);
}
void loop()
{
while(Serial.available())
{
Serial.println("Serial 1 Available");
for(int i=0; i<4; i++) //While data is available read 4 bytes
{
final[i] = Serial.read(); //Read 4 bytes into the array labled "final"
Serial.println(final[i]);
}
for(int i=0; i<4; i++)
{
if(final[i]==correct[i]) //Compare each char received to each car in our password in order
{
Serial.println("Serial 1 Block");
pass_correct = 1; //If we compare two chars and they match, set the pass_correct variable to true(1)
}
else if(final[i]==correct2[i])
{Serial.println("In Block 2");
pass_correct = 2; //Second Lock
break; //End loop and stop comparing chars
}else if(final[i]==correct3[i]){
Serial.println("Wrong block 3");
pass_correct = 3;
}else {
Serial.println("Wrong Password");
pass_correct = 0; // if password does not match;
break; // end of loop stop comparing
}
}
}
while(Serial2.available())
{
for(int i=0; i<4; i++) //While data is available read 4 bytes
{
final[i] = Serial2.read(); //Read 4 bytes into the array labled "final"
}
for(int i=0; i<4; i++)
{
if(final[i]==correct[i]) //Compare each char received to each car in our password in order
{
pass_correct = 1; //If we compare two chars and they match, set the pass_correct variable to true(1)
break;
}
else if(final[i]==correct2[i])
{
pass_correct = 2; //Second Lock
break; //End loop and stop comparing chars
}else if(final[i]==correct3[i]){
pass_correct = 3;
break;
}else {
pass_correct = 0; // if password does not match;
break; // end of loop stop comparing
}
}
}
while(Serial3.available())
{
for(int i=0; i<4; i++) //While data is available read 4 bytes
{
final[i] = Serial3.read(); //Read 4 bytes into the array labled "final"
}
for(int i=0; i<4; i++)
{
if(final[i]==correct[i]) //Compare each char received to each car in our password in order
{
pass_correct = 1; //If we compare two chars and they match, set the pass_correct variable to true(1)
break;
}
else if(final[i]==correct2[i])
{
pass_correct = 2; //Second Lock
break; //End loop and stop comparing chars
}else if(final[i]==correct3[i]){
pass_correct = 3;
break;
}else {
pass_correct = 0; // if password does not match;
break; // end of loop stop comparing
}
}
}
if(pass_correct==1) //If all chars compared match, deactivate(unlock) the lock for 5 seconds
{
Serial.println("Unlocked");
digitalWrite(lock, LOW);
digitalWrite(unlock, HIGH);
delay(5000);
Serial.println("Locked");
pass_correct = 0;
} else if(pass_correct==2) //If all chars compared match, deactivate(unlock) the lock for 5 seconds
{
Serial.println("Unlocked");
digitalWrite(lock2, LOW);
digitalWrite(unlock2, HIGH);
delay(5000);
Serial.println("Locked");
pass_correct = 0;
} else if(pass_correct==3) //If all chars compared match, deactivate(unlock) the lock for 5 seconds
{
Serial.println("Unlocked");
digitalWrite(lock3, LOW);
digitalWrite(unlock3, HIGH);
delay(5000);
Serial.println("Locked");
pass_correct = 0;
}
else
{
digitalWrite(lock, HIGH); //Else if there was not a complete match, keep the lock high(locked)
}
/* FOR TESTING
Serial.print(final[0]);Serial.print(final[1]);Serial.print(final[2]);Serial.print(final[3]);
Serial.print(" | ");
Serial.print(correct[0]);Serial.print(correct[1]);Serial.print(correct[2]);Serial.print(correct[3]);
Serial.print(" ");
Serial.print(pass_correct);
Serial.println("");

delay(500);

当我在串行监视器中输入“AAAA”时，我应该看到已解锁，但我看到...

我的 Arduino 有可能损坏了吗？
有没有可能的方法来解决它？
请尽快提供帮助。
如果我使用此代码：
char final[4];
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial.println("Serial Ready");
}
void loop() {
// put your main code here, to run repeatedly:
while(Serial.available()){
for(int i = 0; i<4 ; i++){
final[i] = Serial.read();
Serial.println(final[i]);
}
}
}
我从串行监视器得到这个：
¿
