The “World’s Largest Arduino Maker Challenge” is happening right now through a partnership between Hackster.io, Atmel, Adafruit, Arduino and Microsoft. Here is a video presentation of the context by Massimo Banzi, CEO of Arduino.cc: The contest will run in multiple phases, the first being an idea submission, by January 15th, 2015. A 1,000 lucky makers… Read More »
In previous posts I covered the steps on programming ATtiny85 and ATtiny84 chips using an Arduino Uno as programmer and the Arduino IDE Software with two different “libraries”. At that time the process of adding new boards to the Arduino IDE was fairly complicated and manual. As of version 1.6.4 of the Arduino IDE, the “Boards Manager” has… Read More »
A simple Halloween themed project to add some animation and sounds to a cardboard skeleton cut-out. A PIR sensor at the top right corner (somewhat hidden under a clump of fake spider web) detects movement and triggers a hobby servo that rotates the torso of the skeleton. The eyes are a pair of red LEDs and… Read More »
I while back I did some work on a self-balancing robot using and Arduino Uno and the InvenSense MPU-6050 6DOF sensor. Using the sensor is easy, thanks to Jeff Rowberg’s I2Cdev library and sample code. If you look around line 200 of the MPU6050_DMP6 example arduino sketch that comes with the library you will see the following:… Read More »
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 »
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 »
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 »
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 »
