FEATURES:
- Works with many different ultrasonic sensors: SR04, SRF05, SRF06, DYP-ME007, URM37 & Parallax PING))).
- Compatible with the entire Arduino line-up (and clones), Teensy family (including $19 96Mhz 32 bit Teensy 3.2) and non-AVR microcontrollers.
- Interface with all but the SRF06 sensor using only one Arduino pin.
- Doesn't lag for a full second if no ping/echo is received.
- Ping sensors consistently and reliably at up to 30 times per second.
- Built-in digital filter method ping_median() for easy error correction.
- Uses port registers for a faster pin interface and smaller code size.
- Allows you to set a maximum distance where pings beyond that distance are read as no ping "clear".
- Ease of using multiple sensors (example sketch with 4 sensors).
HISTORY: 2023-10-15 Changing output from 0 to MAX_DISTANCE if no obstacle is at range. Changing unsigned int to uint16_t, unsigned long to uint32_t
