Arduino – Working with RGB LEDs

This short tutorial will show you how to get started using multicoloured LED’s with Arduino.  Specifically common anode and common cathode and to control the red, blue and green separately.  This means multicoloured blinky lights!  And later, you will be able to see a sample of how to control this with Wi-Fi.

Arduino – Calculating Required Resistor Values

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.

Arduino – Getting started Guide

Getting Started with Arduino

Hi everyone!


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!

Building Self Watering Irrigation for your Backyard (for around 125 dollars)


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.
