Can someone help ??
Reliability Thunder protected, water proof and striking resistant,
Also have you shorted the green and grey wires together?
i already attach picture of connection of rfid to arduino.
i dont know how to troubleshoot.
But thanks for doing so now. It looks like that is wired up correctly?
i also found another manual datasheet from the manufacturer. I have attach below related document. I think it might be helpful..
Then, i tried to apply it in my project, but not working.
So you look with an oscilloscope at the yellow or blue line and see if you can detect any activity.If you can measure the signal and try and determine the baud rate. Then set the same baud rate in your sketch.Then look at the R out signal into the Arduino, is this the right way up for TTL serial data. That is when there is no activity the line sits high? If not then swap over the yellow and blue wires.
and i got reading on an oscilloscope
Then, i dont know how to interface to arduino mega.
So is it the right way up and what is the baud rate?
Just wire it up like you showed. You might want to use one of the Mega's other serial ports like 1, 2 or 3.
Do you have any sample arduino coding for serial read or any related to this RFID reader?
Then i used HyperTerminal software
i already tried serial read in Arduino, but i could not get any reading from arduino serial print.
