Whats an Electric Imp?
It's a Wifi connected processor in a super small package. Check the website for more information - Electric Imp
I purchased the Sparkfun Serial Enabled 16x2 LCD - Black on Green 3.3V to go with the setup.
Here are the hardware and software notes on making it all work.
The Breakout board shown here is dubbed an "April".
Note: This Instructable assumes some basic knowledge of working with an Electric Imp. I have included links to some good resources if you are brand new to the Imp world, but the focus is on getting the LCD working, not teaching the Electric Imp from scratch.
Step 1: Powering and Commissioning your Imp
I chose to power this example via USB which requires the addition of a header and jumper on the April development board. Insert the Imp into the carrier and plug in the USB - he Imp should start flashing a variety of colors when the power is applied.
Follow the steps outlined on the Electric Imp website for Commissioning an imp
Once commissioned, you should get familiar with creating nodes for your Imp and perhaps get "Hello, World!" or some other sample code working before continuing. Some basic knowledge of creating and loading a node is required.
