Publication of the day

I am very glad to announce the first official publication involving the PlainDSP kit and the team behind the scene. We also congratulate Kostas and his team for designing such an awesome detector. Although PlainDSP kits can be used in the context of ludic applications, it provides all the means necessary for the design of much […]

Tilt Sensor (Part 9)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9 RIP my first Adafruit Industries ADXL335 based accelerometer! I used it so much and in so many agressive situations that I managed to break it down! Now, why bother designing a PCB, wasting my time and burning my fingers? I ordered a brand new accelerometer from Adardfruit, via Snootlab.   The new version […]

Sound capture (Part 2)

Part 1, 2, 3, 4, 5 Prerequisites: Understand PlainADC functions which allow analog signals sampling and PlainFFT functions which allow Fast Fourier Transform. Make sure to use the latest versions of these libraries (Please check this page if you are interested in the code.) The purpose of the next coming posts is to exemplify the combined use of PlainADC and […]

Tilt sensor (Part 1)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9 Accelerometers are among the sensors that have experienced the greatest development in the ten past years. From automotive to gaming applications not talking about phones, they are included in many equipements. As a consequence of this massive use, their price is falling down to acceptable prices for the hobbyst! The choice of an accelerometer […]

Sound capture (Part1)

Part 1, 2, 3, 4, 5 On one side we have sound, on the other side we want volts. In between, we need a device which will convert air pressure changes into electrical signal changes: a microphone! The one we will use is of the electret type, nammed after the type of membrane in use. It is small, cheap and […]

Fast Fourier Transform (FFT) (Part 1)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 —————————————————————————— Important notice: The huge popularity of PlainDSP (merge of PlainFFT and PlainADC libraries) and the numerous requests for help drove me to think about a convenient solution for all designers, artists, students, professors, R&D people, prototypists who need to understand, experiment, create systems which feature advanced Digital Signal Processing on Arduino. The result of intense […]
