MicroLS (Part 3)

Part 1, 2, 3 Here is a suggestion of use for the acquired and transformed signal. The frequency spectrum is cut in as many times as the number of leds. The average value of the intensities is computed from each frequency compartment. The level of this average value is compared to a trigger level which switches the leds […]

MicroLS (Part 2)

Part 1, 2, 3 All fun of the project lies in the code! Its construction comes almost trivial and will look like: Set acquisition parameter Endlessly: Acquired data Adjust data Execute FFT Compute frequency spectrum Extract information from spectrum and switch leds on and off accordingly Here is a look and feel about the header of the sketch […]
