Hello, I am seeking some help on this very simple program I was asked to complete. I can't seem to have both my inputs received because after the 1st input, the program jumps straight into the loop (skipping me being able to input the second). I have tried a delay after the first input, but that doesn't seem to help with the system even being able to receive my 2nd input (I type 2nd value and its not recognizing). Any help? Apologies as I know this is probably super easy, I just began learning Arduino. Thank you.
Hardware: Arduino Uno
Instructions: In the Serial Monitor, the user should see the question. What is the first digit of your age? Then the Serial Monitor waits the user to enter one number. Let’s use m to refer to this number. After that, the user should see the question. What is the second digit of your age? Then the Serial Monitor waits the user to enter one number. Let’s use n to refer to this number. After the numbers are entered. The red LED should blink m times and the yellow LED should blink n times.
My Code:
int redLEDPin=8; //Declare redLEDPin an int, and set to pin 9
int yellowLEDPin=10; //Declare yellowLEDPin an int, and set to pin 10
int redOnTime=250; //Declare redOnTime an int, and set to 250 mseconds
int redOffTime=250; //Declare redOffTime an int, and set to 250
int yellowOnTime=250; //Declare yellowOnTime an int, and set to 250
int yellowOffTime=250; //Declare yellowOffTime an int, and set to 250
int m; // number of red blinks
int n; // number of yellow blinks
void setup() // put your setup code here, to run once:
{
Serial.begin(9600);
pinMode(redLEDPin, OUTPUT); // Tell Arduino that redLEDPin is an output pin
pinMode(yellowLEDPin, OUTPUT); //Tell Arduino that yellowLEDPin is an output pin
}
void loop() // put your main code here, to run repeatedly:
{
Serial.println("What is the first digit of your age?"); //Prompt User for Input
while(Serial.available()==0) {} // Wait for User to Input Data
m = Serial.parseInt(); //Read the data the user has input
Serial.println("What is the second digit of your age?"); //Prompt User for Input
while(Serial.available()==0) {} // Wait for User to Input Data
n = Serial.parseInt(); //Read the data the user has input
Serial.println("The Red LED is Blinking");
for (int j=1; j<=m; j=j+1) { // Start our for loop
Serial.println(j);
digitalWrite(redLEDPin,HIGH); //Turn red LED on
delay(redOnTime); //Leave on for redOnTime
digitalWrite(redLEDPin,LOW); //Turn red LED off
delay(redOffTime); //Leave off for redOffTime
}
Serial.println("The Yellow LED is Blinking");
for (int j=1; j<=n; j=j+1) { // Start our for loop
Serial.println(j);
digitalWrite(yellowLEDPin,HIGH); //Turn yellow LED on
delay(yellowOnTime); //Leave on for yellowOnTime
digitalWrite(yellowLEDPin,LOW); //Turn yellow LED off
delay(yellowOffTime); //Leave off for yellowOffTime
}
}
My Serial Monitor:
What is the first digit of your age?
What is the second digit of your age?
The Red LED is Blinking
1
2
The Yellow LED is Blinking
What is the first digit of your age?
Output:
Only the first Age is registered and corresponding LED Blinking
