| /* HC-SR04 Sensor | |
| https://www.dealextreme.com/p/hc-sr04-ultrasonic-sensor-distance-measuring-module-133696 | |
| This sketch reads a HC-SR04 ultrasonic rangefinder and returns the | |
| distance to the closest object in range. To do this, it sends a pulse | |
| to the sensor to initiate a reading, then listens for a pulse | |
| to return. The length of the returning pulse is proportional to | |
| the distance of the object from the sensor. | |
| The circuit: |
| #include <LiquidCrystal.h> | |
| // select the pins used on the LCD panel | |
| LiquidCrystal lcd(8, 9, 4, 5, 6, 7); | |
| // define some values used by the panel and buttons | |
| #define btnRIGHT 0 | |
| #define btnUP 1 | |
| #define btnDOWN 2 | |
| #define btnLEFT 3 |
