Serial.print(currentTime - timer);
Serial.println(" ms");
} else if (flag == 1) {
Serial.println("Wrong Click!");
}
flag = -1;
}
This is the function that will be triggered when button 1 is pressed. When button 1 is pressed, if the
flag is 0 at this time, the response time will be printed, otherwise the press error will be prompted.
4. About pressed2() function
void pressed2() {
if (flag == -1) {
return;
}
if (flag == 1) {
int currentTime =millis();
Serial.print("Correct! You reaction time is : ");
Serial.print(currentTime - timer);
Serial.println(" ms");
} else if (flag == 0) {
Serial.println("Wrong Click!");
}
flag = -1;
}
This is the function that will be triggered when button 2 is pressed. When button 2 is pressed, if the
flag is 1 at this time, the response time will be printed, otherwise the press error will be prompted.
4.6.6 6.6 Guess Number
Guessing Numbers is a fun party game where you and your friends take turns inputting a number (0~99). The range
will be smaller with the inputting of the number till a player answers the riddle correctly. Then the player is defeated
and punished. For example, if the lucky number is 51 which the players cannot see, and the player 1 inputs 50, the
prompt of number range changes to 50~99; if the player 2 inputs 70, the range of number can be 50~70; if the player 3
inputs 51, he or she is the unlucky one. Here, we use IR Remote Controller to input numbers and use LCD to output
outcomes.
