Homework 2

Arduino Serial Input and Output

Modify the code provided in class to achieve the followings. You can choose either option to complete. Students who choose option 2 can have 1 bonus point on the total grade of this class. For example, if your accumulated final grade is 89, having this point will make it 90.

Option 1:

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. Lets 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. Lets 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. The serial monitor should produce something like the following.

Please print out your unique serial output here as my example and paste your code in this document. Then turn in the word file through blackboard link.

Option 2: Make your invention to be a holiday gift.

Step 1. Instead of printing What is the first digit of your age, the monitor prints What is the digit representing the month of your birthday?. Instead of printing What is the second digit of your age, the monitor prints What is the digit representing the day of your birthday?. For example, if a birthday is Feb, 7^th. These two digits should be 2 and 7. Make the system work for this situation. After the blinking, the serial monitor shows, Happy Holidays! You are very special and I love you.

Step 2. Show the system to one of your friend. Record his or her name, and record what he or she says. Type them here. Students must complete this part to get the bonus point.

Then turn in the word file through the blackboard link.
