Hello,
I'm a beginner in the Microcontroller World. I recently purchased a RFID reader. It is a usb device which, when plugged to my computer, will be recognized as an imput device and with notepad open and RFID chip read, it will send data to notepad. Is there a way I can connect arduino to the device(without computer) and receive that data? I have an Arduino UNO, MEGA, or MINI that I can use if either is better.
Thanks for your time,
Greg
Is there a way I can connect arduino to the device(without computer) and receive that data?
Without knowing specifically what the device is, that's impossible to answer. My impression, though, is that it is a USB slave, just like the Arduino. Without a USB Master/Host involved, the slaves just sit around all day drinking beer.
You need a USB Host (shield) to make the slave do anything. Writing the driver is not a beginner project.
You'd be better off getting an RFID reader that is more compatible with the Arduino and less compatible with the PC.
Thank you for the information. I purchased another on Ebay that says it is Arduino compatible. Do any know of some code that would read rfid chip and if on the active list, turn on a small motor or led?
Thanks again for your input or time into this.
