This part is an extension to lab05-Part02 in using Arduino grove board. In this part we are going to use the buzzer and the button on the board to make an alarm clock. Basically, you should use the knowledge developed in Lab05-Part2 for connecting the board to java using Firmata libraries and modify the provided code below. A portion of the main method, and a method (getAlarmDate) for taking the keyboard entries are provided along with the necessary/useful classes/methods. 11 Grove Beginner Kit For Acting Har 642 GROVE seeed

Please reenter your desire date");
You should develop the rest of the main method (as mentioned in the program above) such that your program runs as below: 1- The program asks user to enter the desire alarm date and time. You should use the getAlarmDate method for this.
2- Your code should check continually whether the current time has passed the entered date or not. (Hint: search whether date1.after(date2) or date1.before(date2) from java.util.Data is useful) 3- Right after the current time passes the alarm time, Arduino buzzer should start beeping for 30 times. The buzzer beep should be set up as 100 milliseconds on and 100 milliseconds off. Hint: see the LED-specific statements in Lab05-Part2, see if those statement can be modified for the buzzer as: var myBuzzer =myGrove Board.getPin(5); myBuzzer.setMode(Pin.Mode.PWM); myBuzzer.setValue(X); (for example, see if myBuzzer.setValue(20) can turn it on and myBuzzer.setValue(-1) can turn it off.) 4- Note that you should be able to stop the buzzer by pressing the button for less than half a second. Hint: see the LED-specific statements in Lab05-Part2, see if those statement can be modified for the button as: var myButton =myGroveBoard.getPin(6); myButton.setMode(Pin.Mode.INPUT); myButton.getValue() can gives the signal from button. If you do not press the button and run myButton.getValue(), your program receives O. and if you press the button and running myButton.getValue(), your program receives 1.
