MPU6050 Interfacing with Raspberry Pi using ‘C’

Introduction:

  • MPU6050 sensor module is an integrated 6-axis Motion tracking device.
  • It has a 3-axis Gyroscope, 3-axis Accelerometer, Digital Motion Processor and a Temperature sensor, all in a single IC.
  • It can accept inputs from other sensors like 3-axis magnetometer or pressure sensor using its Auxiliary I2C bus.
  • If external 3-axis magnetometer is connected, it can provide complete 9-axis Motion Fusion output.
  • A microcontroller can communicate with this module using I2C communication protocol. Various parameters can be found by reading values from addresses of certain registers using I2C communication.
  • Gyroscope and accelerometer reading along X, Y and Z axes are available in 2’s complement form.
  • Gyroscope readings are in degrees per second (dps) unit; Accelerometer readings are in g unit.

Adding USB Attached GPS to your Raspberry Pi Projects

This quick learning guide will show you everything you need to do to add position tracking to your Pi project using the open source GPS daemon ‘gpsd’ and an inexpensive USB to TTL adapter cable or via direct-wiring to the built-in Pi UART pins

Please note this guide installs a system service called gpsd which you can then query for data. You may be better off just using pure python to read data from the GPS, its less complex in many cases

Build a Stratum 1 NTP (Time) Server

The Raspberry Pi Model B was released in 2012 and, since then, a number of useful applications regarding this device have ensued. However, one particular application that is seldom overlooked when dealing with the Raspberry Pi is its ability to be used as a Stratum 1 NTP server and allow you to synchronize clocks across networks like the Internet. For me, this useful trick has actually made my entire office far more efficient.

Video Streaming with Raspberry Pi Camera

In this post we’re going to show you how you can do video streaming with a Raspberry Pi and a Raspberry Pi Camera – how to stream live video into a web page that you can access in any device that has a browser and is connected to the same network the Pi is. This is useful to apply to a home surveillance camera, for example.

Prerequisites:

  • You should already be familiar with the Raspberry Pi board
  • You should have the Raspbian or Raspbian Lite operating system installed in your Raspberry Pi
