Udp NTP Client with DNS
I updated the example code to use DNS resolution from the Arduino 1.0 IDE
Basically tries to use the load-balanced NTP servers which are
"magically" returned from DNS queries on pool.ntp.org
If DNS fails, fall back to the hardcoded IP address
for time.nist.gov
bearpaw7 (github), 01DEC2011
This code is also in the public domain.

- exemplo que mostra como incluir html, css,
javascript e imagem em arquivos no sdcard e também
como fazer download de um arquivo pdf do sdcard.
