Whistle Timer ///

loudness sensor, LED bar/////

see if you can whistle long enough to fill the lights on the LED bar

This lab involves using a loudness sensor to activate a while loop. The purpose is to set up the sensor so that while it detects a whistle it will cause the LED to display a timer which increases incrementally as time progresses. When the loudness sensor is no longer activated the timer will stop, ending the loop. When another whistle is detected the timer will restart.

Implementation considerations: While the first condition (Has user activated loudness sensor?) remains false, no sound is generated. When a whistle is detected and the timer begins, the timer will continue until the condition is again evaluated as false, ending the loop. As long as the sensor remains activated, the condition will continue to be evaluated as true and the timer loop will continue. While the sensor remains activated, the LED timer bar will increase incrementally, displaying one additional bar for each second of continual activation.

The LED bar increases by one block each second; the LCD shows the users whistle time

//Required at beginning of each lab file - initialize Arduino and other hardware. initLab(); initBar();
