Bluetooth multiple serial connections with Linux
In a previous post about bluetooth we have seen how to connect to a low cost HC-06 or Sparkfun Mate Gold module connected to an Arduino and establish a serial communication with it using minicom.
Bluetooth with Linux – Send and Receive data
Bluetooth Post Updated on Feb 2017! We have already used a bluetooth module with an Arduino in Using Blueetooth Mate Gold in your Arduino project. In this post we would like to open a serial
Gyroscope – Filtering angular velocity spikes
In this post we will use Matlab to filter angular velocity data acquired with an Arduino. The gyroscope we will be using is a tri-axis L3G4200D sensor. In a previous post - Can you roll
[Quick] Filtering Gyroscope data with Matlab
In this post we will use Matlab to filter simulated data. We will suppress low frequency components with a high pass filter. You can apply what follows to remove periodic trends of a specific frequency
Matlab Arduino – Setup a serial communication [Quick]
Updated on Jan 2017! In this quick post we will write a Matlab script and a Arduino sketch to read and write serial commands. Arduino side This sketch is really simple, we will initialize
Working with Adxl335 accelerometer and Arduino
We have already used an accelerometer in a previous post. This time we have an analog 3-axis accelerometer, ADXL335, which can be used to estimate the orientation along the x,y and z axis. There are
Can you roll with a L3G4200D gyroscope, Arduino and Matlab?
Angular velocity with Arduino In this tutorial we will use the L3G4200D sensor from STMicroelectronics. This gyroscope measures angular rates about three axes. They are referenced as x, y and z. The
Using Bluetooth Mate Gold in your Arduino project
Updated on February 2016! With the Bluetooth Mate module from Sparkfun you can add 2.4GHz wireless communication to your robot. It is designed specifically to be used with the Arduino, any serial stream from 2400
Magnetometer – Where are you heading?
In this post we will use a magnetometer to measure relative angular position with Arduino. We will be using the CMPS10 module which is a tilt compensated compass from Robot Electronics. This sensor uses a
Using an accelerometer in your Arduino project
In this post we will introduce accelerometer sensors and share a few examples on how to interface them to the Arduino. The sensor we will be using is a MMA7260Q from Freescale Semiconductor, a low
Xbee communication between an Arduino and a computer
Need a Wireless communication? Use the Xbee If you are looking for a wireless solution to a communication problem, the Xbee modules might be the answer. These modules can be used to connect an Arduino
