1  Using Arduino / Project Guidance / Re: Need help with MFRC522 on: May 31, 2012, 02:04:58 pm
I found the attached code on Simon's blog and another friend recommend this to me. I translate to English the comments. This code is using SPI communication but my kit is using UART, still a good example.

Thank you John,

But i already test this code and works then i was able to record the card serial number (4 bytes) in an array, but then I'm not bale to do something else, maybe i need to be more patient and investigate more.

Also i would like to know is somebody have a sample code using the basic instructions set, then i will be able to use the other features this kit has.

Regards

Hello,

Any luck with your project?

I bought another kit based on the same MFR522, mine is this one:

 http://www.ebay.com/itm/Serial-UART-13-56MHZ-RFID-Reader-Writer-Module-with-Cards-Arduino-Compatible-/130649910994?pt=BI_Electrical_Equipment_Tools&hash=item1e6b576ed2

My project will consist of

•   RFID access control, read a tag and grant access if is in a database.
•   Access log; want to have a log when access is granted to a tag.
•   Web, want to be able to set up new cards or verify log file from a web server.
•   Use a LCD as a basic HMI to the user

Maybe looks a little complex, but want to go step by step, so far I have been a little frustrated because I only can read the tag and show the serial number in the serial monitor and record the tag serial number in an array, but that is all. So still in step 1! :'(

Maybe my problem is handling information in an array, I don’t know.

Maybe we can combine efforts and make our systems work.

Regards

Hello,

Hopefully somebody can show me the pad to make my RFID kit the way i want.

I newbie using Arduino but want to become an expert, I’m a self-learning guy, like to read and practice what I’m learning.

De way I decide to learn Arduino is to make a project, so I chose a RFID access control and log system.

My project will consist of

•   RFID access control, read a tag and grant access if is in a database.
•   Access log; want to have a log when access is granted to a tag.
•   Web, want to be able to set up new cards or verify log file from a web server.
•   Use a LCD as a basic HMI to the user

Maybe looks a little complex, but want to go step by step, so far I have been a little frustrated because I only can read the tag and show the serial number in the serial monitor and record the tag serial number in an array, but that is all.

Have somebody a sample code that can share with me?

6  Using Arduino / Project Guidance / GPS + GSM-GPRS + Bluetooth on: November 01, 2011, 06:26:34 pm
Hello,

I'm new on Arduino and I want to start working with on a GPS project.

I would like to have the Arduino GPS and SMS (GPS) capable, also I would like it to record a log of coordinates as well as some other info as time in i.e. then it needs to be able to download the log to my PC using Bluetooth so I will build a route map on my PC track system (working in the development too).

What Arduino board and shields do you recommend me to buy for my prototype?

Thank in advance for your help.
