[Saurabh] wanted a quick project to demonstrate how easy it can be to build devices that are voice controlled. His latest Instructable does just that using an Arduino and Visual Basic .Net.
[Saurabh] decided to build a voice controlled lamp. He knew he wanted it to change colors as well as be energy-efficient. It also had to be easy to control. The obvious choice was to use an RGB LED. The LED on its own wouldn’t be very interesting. He needed something to diffuse the light, like a lampshade. [Saurabh] decided to start with an empty glass jar. He filled the jar with gel wax, which provides a nice surface to diffuse the light.
The RGB LED was mounted underneath the jar’s screw-on cover. [Saurabh] soldered a 220 ohm current limiting resistor to each of the three anodes of the LED. A hole was drilled in the cap so he’d have a place to run the wires. The LED was then hooked up to an Arduino Leonardo.
The Arduino sketch has several built-in functions to set all of the colors, and also fade. [Saurabh] then wrote a control interface using Visual Basic .Net. The interface allows you to directly manipulate the lamp, but it also has built-in voice recognition functionality. This allows [Saurabh] to use his voice to change the color of the lamp, turn it off, or initiate a fading routing. You can watch a video demonstration of the voice controls below.

I didn’t have voice control on my jar but it did have bluetooth!
These lamps make good projects. They don’t take too long to make and they are something you can easily keep and display.

I see what you did there xD
