View in browser DFT BASICS For some electronics hobbyists, the discrete Fourier transform, or DFT, is a feared and mysterious entity.   For some electronics hobbyists, the discrete Fourier transform, or DFT, is a feared and mysterious entity that is best left to the "experts" or those who practice in the field of digital signal processing (DSP) on a daily basis. The truth is, however, that with a little explanation and only a dash of simple math, anyone who can use a spreadsheet or program a microcontroller can understand and put this powerful signal processing technique to work in no time at all.

Advertisement MAKE YOUR LED DANCE JUST LIKE A CANDLE Modulate an LED to respond to the world around it with this simple technique.   If all we do with an LED is use it for steady, dull, boring illumination, we are leaving so much of their performance on the table. Instead, why not take advantage of an LED's ability to quickly respond to a changing current, and modulate their drive current to turn your room into a responsive environment? Find out how to make any LED dance to the small randomly unstable air currents that make candles flicker. The technique can be applied to turn any environmentally sensed input into an LED's or light bulb's brightness. Try It Now!

View Specs & Applications Advertisement DETECTING SOUNDS WITH THE SONIC SENSOR Put your appliances under sonic control with this super souped-up version of a "clapper."   If your pastimes include fiddling with microcontrollers, then you've probably already experimented with sensing light, temperature, humidity, infrared, touch capacitance, and so forth. Have you ever considered brewing up a circuit that will respond to sound? This is a fun project with lots of unusual applications in the areas of home security and remote control. Read It Now! MakerPlot — THE DIY SOFTWARE KIT PART 5 Graphical plotting, data acquisition, and control software for your microcontroller.   An important function of MakerPlot is its bi-directional capabilities.
