Access your Raspberry Pi Terminal and Graphical Desktop remotely using SSH and VNC

This post will cover the steps necessary to set-up remote access to the Raspberry Pi terminal and graphical desktop environment from a Windows, or Linux PC. I do not have a Mac, but the steps should be very simillar. In some posts this is referred to as running your Raspberry Pi “headless”. I want to put my Raspberry Pi 2… Read More »

Experimenting with Sound Localization and Arduino

Today I’m going to walk you through my experience trying to localize the source of a sound using Arduino. My goal with this was to add a feature to my robot that would make it more interactive and look more “alive”. Beta 1 What you normally see people doing, as an easy approach, is to… Read More »

Raspberry Pi 2 Initial set-up and configuration with NOOBS / Raspbian

Unlike the Arduino, the Raspberry Pi is not a micro-controller, but rather a small, bare-bones computer that needs an operating system in order to run. The most popular OS for the Raspberry Pi currently is a version of Linux, called Raspbian, specifically optimized for its hardware. I plan to use Raspbian exclusively on my new Raspberry Pi… Read More »

Raspberry Pi 2 for Robotics

I just got a Raspberry Pi 2 in my hands and hope with its help to add some cool features to my new robot projects, beyond the capabilities of the trusted Arduino. The specific goal, besides just tinkering around with something new, is to get basic computer vision working, using OpenCV and a webcam, or the Raspberry Pi Camera… Read More »

Bipolar stepper motor control with Arduino and an H-Bridge

It is a well known fact that Stepper motors are awesome! The only downside is that they can be a bit trickier to get going than servos and plain old DC motors. If you are interested in the inner mechanics and theory of stepper motors, check this excellent post on PCB heaven. If you happen to have one… Read More »

Arduino Joystick Module Example

In one of my rather frequent eBay visits, I came across a nifty little joystick module, much similar to the analog thumb-stick on the PlayStation 2 controllers. The module is very easy to use with an Arduino uno and only costs a few dollars. Several different versions are available from eBay, Adafruit, Sparkfun and other… Read More »
