kandi X-RAY | Arduino-RFID Summary
This is an RFID authentication system. It allows a person to place an RFID tag within proximity of the reader device (usually 5-6 inches with this reader) and it will look up the tag in an SQLite database to check if it should grant access. If authorization is granted, the hardware device will turn a servo motor into a second position. The primary application of this being the unlocking of a door. This implementation also speaks aloud "Access Granted" or "Access Denied" if you are running the server on OS X. You can modify the source to use something like flite on other OSes. This project is very easily modified to do any sort of task. Some ideas are:. Here it is in action. .

QUESTION
I'm using an 125Khz RFID module RDM6300 with arduino nano. While the card is near the RFID reader the loop will read the card multiple times. I want it to read only once while the card is near the reader then read it again if a new connection is being made. *This code is not writen by me, this is the source: https://github.com/Wookai/arduino-rfid
...ANSWER
Answered 2018-Feb-13 at 07:18You can set a delay (e.g. delay(2000)
) after reading the (end of tag). A delay of (say) 2 seconds will allow the user to move the card far enough away from the reader. Note that delay
is a blocking command which might not suit your purposes, in which case you could be looking at using the millis
count to activate/deactivate the Serial.read
.
Another option is to accept the multiple reads, but keep a state of which card has been read. If the new card number is the same as the old card number (within a reasonable timeframe) then just ignore.

Install Arduino-RFID
You can use Arduino-RFID like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
