Pololu-Zumo-Shield-Arduino-fonctionnalites (voir la source)
Version du 9 avril 2017 à 14:19
, 9 avril 2017 à 14:19→Buzzer
The Zumo Shield comes with a buzzer that can be used to generate simple sounds and music (for example, you could use it to produce an audible countdown at the beginning of a sumo match). The buzzer control line is labeled BZ on the shield; if you alternate between driving it high and low at a given frequency, the buzzer will produce sound at that frequency.

The [[Pololu-Zumo-Shield-Arduino-bibliotheque-Zumo|ZumoBuzzer library]] uses hardware PWM to play notes on the buzzer, with '''digital pin 3''' (OC2B) on an Arduino '''Uno''' or an older Arduino, or with '''digital pin 6''' (OC4D) on an Arduino '''Leonardo''' or '''A-Star 32U4 Prime'''. A jumper is provided to connect the BZ input to the appropriate Arduino output, as detailed in Section 3.c.

== Zone d'extension avant ==
A number of I/O, power, and ground connections are brought to the front of the Zumo Shield to allow the mounting of additional sensors and other components. The pinout of this front expansion area is detailed in [[Pololu-Zumo-Shield-Arduino-extension-avant|Section 3.b]].
== Senseurs Inertiels ==
The Zumo Shield includes on-board inertial sensors, which can be used to sense acceleration and orientation for advanced applications:
* The '''v1.2''' Zumo Shield features an '''LSM303D''' 3-axis accelerometer and magnetometer and an '''L3GD20H''' 3-axis gyroscope.
* The '''original''' Zumo Shield features an '''LSM303DLHC''' 3-axis accelerometer and magnetometer.
The inertial sensors are detailed in [[Pololu-Zumo-Shield-Arduino-extension-avant|Section 3.d]].
