"Too Close" Trigger with Blinking
/* Code generated by RoboBlockly v2.5 */
/* Problem Statement: 
    Modify the pre-placed code so that the "too close" distance
    is 6, and it blinks red while reading the sensor and blue
    (pin 11) after it stops.
    */
#include <arduino.h>

// Keep reading sensor until distance less than 6
// Blink red LED while reading, then blue at end,
// using digitalWritehighLowForeverNB for blinking
// Set up blue and red LED pins (11 and 13)
pinMode(11, OUTPUT);
pinMode(13, OUTPUT);
// Set up trigger (9) and echo (8) pins for sensor
pinMode(9, OUTPUT);
pinMode(8, INPUT);
// Start red blinking using nonblocking code
digitalWriteHighLowForeverNB(13, 250, 250);
// Keep reading sensor until distance < 6
waitUntilUltrasonicSensor(9, 8, 6);
// Done: stop red blinking
digitalWriteOff(13);
// Do 4 blue blinks and display message
