Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.
Let's look at the first application of Fourier transforms by creating an audio spectrum analyzer. runs with a sample rate of 9000 hz and an FFT size of 256.
This is an audio spectrum VU meter using the LoL Shield for Arduino. This project uses a Fast Fourier Transform library for Arduino to analyze an audio signal.
Using FFT algorithms were successfully implemented in low power MCU. You can find a great example of Chan's FFT. It serves as a great reference for running FFTs
This project implements a realtime audio spectrum analyser using a PIC18F4550 8bit microcontroller. FFT maths is complex and I dont pretend to fully.

Android is a great platform to start building your apps, but its not the simplest to start with. For that reason we at hobbyist have built a kit which will take you through the process of building an App step by step.
Gardening in the modern age means making things more complicated and arduous, with electrons, bits, and bytes. Combining microcontrollers and gardening is a really popular idea. I think that’s because gardens have very simple inputs and outputs that are easy to wrap your head around.
I wanted a smartwatch that showed me notifications from an iPhone, was small enough to wear, and had a rechargeable battery that lasted for at least a day. I created my own Apple watch based on an Arduino. It is a smartwatch based on an Arduino mini pro, which is connected to the iPhone over Bluetooth.
First of all, you need a suitable IoT gateway with a couple of free GB hard disk space (libraries can be heavy sometimes). Follow the Getting Started section of Create to get your Gateway up and running (choose Ubuntu distribution, for example).

If you\'re like me, then you have a small pile of clothes on the floor that may or may not be dirty. This could include jeans, dress shirts, and barely worn shorts. So how can you tell which clothes are clean or dirty? I came up with a way to track various articles of clothing using NFC and a Raspberry Pi.
