Detailed Description

The pin definitions.

Each ultra sonic sensor has one trigger and one echo pin. Both pins a re needed in order to conduct a measurement.

Variable Documentation

FRONT_ECHO

const uint8_t UltraSonic::Pin::FRONT_ECHO = 23

Echo pin front.

The time between two edges on this pin is used to calculate the distance.

FRONT_TRIGGER

const uint8_t UltraSonic::Pin::FRONT_TRIGGER = 4

Trigger pin front.

This pin is used in order to start an ultra sonic measurement in the front.

LEFT_ECHO

const uint8_t UltraSonic::Pin::LEFT_ECHO = 22

Echo pin left.

The time between two edges on this pin is used to calculate the distance.

LEFT_TRIGGER

const uint8_t UltraSonic::Pin::LEFT_TRIGGER = 5

Trigger pin left.

This pin is used in order to start an ultra sonic measurement on the left.

REAR_ECHO

const uint8_t UltraSonic::Pin::REAR_ECHO = 17

Echo pin rear.

The time between two edges on this pin is used to calculate the distance.

REAR_TRIGGER

const uint8_t UltraSonic::Pin::REAR_TRIGGER = 18

Trigger pin rear.

This pin is used in order to start an ultra sonic measurement in the rear.

RIGHT_ECHO

const uint8_t UltraSonic::Pin::RIGHT_ECHO = 27

Echo pin right.

The time between two edges on this pin is used to calculate the distance.

RIGHT_TRIGGER

const uint8_t UltraSonic::Pin::RIGHT_TRIGGER = 12

Trigger pin right.

This pin is used in order to start an ultra sonic measurement on the right.
