##VGG16 model for Keras
This is the Keras model of the 16-layer network used by the VGG team in the ILSVRC-2014 competition.
It has been obtained by directly converting the Caffe model provived by the authors.
Details about the network architecture can be found in the following arXiv paper:
Very Deep Convolutional Networks for Large-Scale Image Recognition

Analog Input | |
Demonstrates analog input by reading an analog sensor on analog pin 0 and | |
turning on and off a light emitting diode(LED) connected to digital pin 13. | |
The amount of time the LED will be on and off depends on | |
the value obtained by analogRead(). | |
The circuit: | |
* Potentiometer attached to analog input 0 | |
* center pin of the potentiometer to the analog pin |
