Lesson 16 GY-521 Module
Overview
In this lesson, we will learn how to use GY-521 module which is one of the best
IMU (Inertia Measurement Unit) sensors, compatible with Arduino. IMU sensors like
the GY-521 are used in self balancing robots, UAVs, smart phones, etc.
Component Required:
(1) x Elegoo Mega2560 R3
(1) x GY-521 module
(4) x F-M wires
Component Introduction
GY-521 SENSOR
The InvenSense GY-521 sensor contains a MEMS accelerometer and a MEMS
gyro in a single chip. It is very accurate, as it contains 16-bits analog to digital
conversion hardware for each channel. Therefore it captures the x, y, and z channel
at the same time. The sensor uses the I2C-bus to interface with the Arduino.
The GY-521 is not expensive, especially given the fact that it combines both an
accelerometer and a gyro.
