A question about the two USB jacks.

Posted: 18 Feb 2013 01:44 AM PST

I recently received my DUE smiley-grin and I have a couple micro USB cables on their way. I was just looking over the board and noticed that the USB slots are shaped just slightly different. The native port is rectangular and the programming port id "D" shaped....

Ok. Thanks for the advice on frequency. Do they make Arduino UHF RFID readers? If so, who sells it?

As for the toolboxes, they are similar to this:

Grazie per la risposta ma non mi è tutto chiaro.
Il transil, da quello che ho capito, mette in corto il positivo e la massa al superamento di una certa soglia.
E che resistenza ci devo mettere? Parlo anche di potenza della resistenza.

I never said the tools were metal  smiley-wink

I'm more concerned with having a system that can read and track tags right now than for using it in day-to-day operations. Eventually, though, I will want to use it throughout the company.

Buenas:

No te compliques mucho con la temperatura y la humedad, con un solo sensor de temperatura te deberia de valer para medir esta, y la humedad no te sera facil de controlar aunque la midas, pon una resistencia de calefacion pequeña, es decir no po...

Ciao,
hai provato a fare una ricerca sul forum?
Ci son parecchi thread sul tema.. così inizi a farti un'idea e a scrivere qualche riga di codice  smiley-wink

Re: Beginner - 30x9 LED board

Great. I have been able to find a local store that has those specific shift registers but I don't know anything about anodes and all I can find when searching is switches / dials that are anodized.

Is there a specific product number for an anode that w...

If you put an RFID tag onto a metal tool then it will no longer read. The metal stops the tag from working.

Yes it could be noise pickup on the line. Solder some surface mound decoupling caps between the pins on the underside of the PCB.

Rieccomi. In tutta la mia nabbaggine non ho idea di come realizzare il progetto come da titolo. Devo realizzarlo come tesina, qualcuno potrebbe auitarmi con qualche snippet di codice oppure spiegazioni... Il prof continua a non spiegarci come si fanno ...
