That the formatting and indenting are terrible. Make the code easy to read by putting each { on a new line, by putting each } on a new line, by putting no more than one statement on a line, and by using Tools + Auto format to fix the horrid indenting.
I just know it now, Thanks, i already use Tools + Auto format and update the code...
- the tag read at rfid shows 1 by 1 at the LCD and Serial Monitor
Because that's how you tell it to appear. How do you want it to appear?
I want the LCD and Serial Monitor just showing the RFID tag/card number. (only the number below the number that i mark with yellow)
Can you give me solution on how to do it, and what coding should i modify?
Serial.print()ing an int causes it to be converted to a string. Serial.print() of a char that contains the same value as the int will produce quite different output, and I suspect that is the output you are expecting.
Dont really know what u mean, can u explain it or show me the example with my coding?
Unlikely, since you appear to have the LCD connected to pin 9, too.
You have not declared pin 9 to be an output, nor do you have any code that affects pin 9.
So i need to declare other pin as a output for buzzer? and how do i make the buzer to beep when the RFID tag/card is touch?
Thanks in advance.
