| 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. | |
