// This example shows how to send a JSON document to a UDP socket.
// At regular interval, it sends a UDP packet that contains the status of
// analog and digital pins.
// The JSON document looks like the following:
// It looks like that:
// {
// "analog": [ 0, 1, 2, 3, 4, 5 ],
// "digital": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 ]
// "analog": [0, 76, 123, 158, 192, 205],
// "digital": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0]
// }
//
// If you want to test this program, you need to be able to receive the UDP
