Ultrasonic Ranger(Ping)(One Pin)

File:TArduinoUltrasonicPing.png

Summary

One-pin ultrasonic ranger module for distance measurement. Provides analog output for distance, digital timeout indicator, and ping trigger/echo control.

Description

The Ultrasonic Ranger (Ping) module measures distance using ultrasonic pulses. It uses a single pin for triggering and receiving echoes. The module can be enabled or disabled, and includes configurable pause time, ping time, timeout, and output units (cm, inches, or raw time). If no echo is detected within the timeout, the module outputs a predefined timeout value.
