Answer 1

String readString;
int count = 0;

void setup() {
Serial.begin(9600);
}

void loop() {
while (Serial.available()>0) {
readString = Serial.readString();
if(readString == "1234567") {
int i;
for(i = 1; i <= 6; i++) {
readString = Serial.readString();
if(i == 1) {
if(readString == "1234")
count++;
}
if(i == 2) {
if(readString == "2345")
count++;
}
if(i == 3) {
if(readString == "3456")
count++;
}
if(i == 4) {
if(readString == "4567")
count++;
}
if(i == 5) {
if(readString == "5678")
count++;
}
if(i == 6) {
if(readString == "6789")
count++;
}
if(i == 7) {
if(readString == "7890")
count++;
}
}
}
if(count == 7)
lcd.print("we are ready.");
}
