Hi,
last year I needed a neural network for my Arduino for color recognition - just give it RGB inputs from an RGB sensor and wait for output - “red”, “green”, “orange” - whatever. I love FANN (Fast Artificial Neural Network) library by Steffen Nissen so I decided to use it. After a week or so I had a working Arduino C++ port of vital functions of the original C version of the library. I call it FANNduino. Although the port is not finished yet (many many many functions are still missing), I want to share it with you.
You can download FANNduino [here.
It is surprisingly fast and I am working on adding more of the original functions, so stay tunned for updates. I hope you will find this library useful for your projects :-)!](http://fannduino.com/)
