Have you ever hooked something up to power … and noticed it either smoking or a strange pop followed by silence or a broken device? The most common cause is too high of a voltage. Every component on your electronic devices can only handle voltages up to a certain point. I’m going to show you a simple formula to calculate the required resistor values when working with Arduino.

For users brand new to Arduino, the pin system can be a little bit confusing. So I thought covering them in a very high level detail may help before we get too far. By the end of this tutorial set, you will be able to use input and output on an Arduino. And you should have a good understanding of resistors and LEDs.

Getting Started with Arduino
Today is an exciting day. I was recently asked to write a series of articles focusing on Arduino for Connectedly and what better way to get started than to write up a quick getting started article!
What Does It Do
Have you ever wished you could remotely control devices at your home? Or wanted to log information like the outdoor temperature for a full year? Or maybe create a solar powered blinking t-shirt? These things are all relatively easy now thanks to Arduino.
What To Expect
I consider myself a tinkerer or maybe even a mad scientist in some circles. If you imagine my house as covered in electronics and gizmos… well you would be absolutely correct! I come from a software development background (you may recognize me from my BlackBerry 10 applications and games) and I have worked with electronics for a long time.
Throughout these articles, I will walk you through using an Arduino development board. We will start with the very basics, and move to the more advanced. And hopefully you will catch the excitement I have for this platform!

You may notice I have started posting a more diverse set of information and instructions!
Well, I’ve also started writing for a new tech site from Mobile Nations called Connectedly. This doesn’t mean less articles here, just that the content will be more diverse. So feel free to come join me on my Connectedly articles as well!

I thought this might be a fun one to share. This requires no programming, and no fancy hardware. Just a little bit of elbow grease.
When I first moved into my new home with my significant other, I fell in love with the backyard. I built my own little greenhouse and quickly expanded it to a mini garden with some stand up pots. And now the veggies I grow last us year round. One of my challenges I quickly encountered: I work many contracts and have many hobbies. Being home at off hours, how can I easily make sure my plants stay watered?
The easy way was to build a very simple irrigation system.

As previously announced, I am proud to announce a brand new Raspberry Project! This time I ordered my parts from Newark Canada after reading about their involvement with the Raspberry Pi.
This fun little project is intended to show off some great little features from this mini-PC. To show users how to leverage some of the functionality of the unit.
What is a Ghost Hunting Box
A ghost hunting box collects various pieces of information often outside the visibility of a normal person. In our case, we are going to give the person the ability to see invisible objects, detect temperature changes and collect audio.
