IoT – Internet Of Things




The Internet of Things, also called IoT is a new trend in which objects, animals or people have unique ability to identify, transfer its data over the internetwork without any or less human intervention, just machine actions that converges sensors, the internet and machines as gateways.

The “thing” is a device capable to be in a living object or inert one such as a tracker system, smart meter, radiation sensing for map radiation construction, connected toothbrushes, etc.

Learn about internet of thing concepts.  What is? The framework models, cloud storage services and why is it growing fast.  Read more.


Play with is LabVIEW example that feeds Xively Cloud Service and make a few triggers, this gives more better understanding of what you could do with the internet of things.

XBee Series 1 Basic Tests

XBees are regular RF modules with capabilities of Mesh networks.  It are based on 802.15.4 wireless standard named Zigbee.  Although they are not full zigbee compliant modules, the company has a variety of fancy modules and there are ones that are full zigbee compliant.

Zigbee is regularly used to make control applications where battery life saving is very important.  Check out the tutorial.

Computer Vision

Computer Vision is an art.  For those people that made the libraries, my total admiration.  I will show you here the basic of displaying an image using your computer with a package named OpenCV or Open Computer Vision.  This stack of functions will help you to develop complex applications using your device input, generally a camera using your PC.  Nowadays you can use a FPGAs with a wrap of functions using Vivado, and Zynq Xilinx

CPLDs – Complexity Reduced to One Single Chip

CPLDs are the most basic chips (right now) in programmable logic.  You can make an AND, OR; make combinational gates, state machines and any combination of circuitry hardware that you want.

Its well suited to glue logic to get the cost of hardware production lower.  I will explain a very basic introduction of CPLD and design flow to follow.

Finally i will leave you the JTAG interface schematic and some VHDL files for you to test.  To view this entry go here.

Resistive Load Control

Microcontrollers are good for control.  8-bit market stills rules.  In this project i was able to implement a simple way to dim the incandescent light bulb.  This project was submitted on the IEEE design contest locally, but unfortunatelly i was only able to be on the second place.

In the link you will find how i did that.
