Microcontroller › 8051 › RFID based Secured access system using 8051 microcontroller (AT89C51)
Hi….I am referring to the project "RFID based Secured access system using 8051 microcontroller (AT89C51)" by Himanshu Chaudhary. I want to know what Rfid module has been used. I have rfid rc522 and EM-18 but no one seems working. Moreover, in the circuit diagram of the same project, only pin no. 5 and 2 of the module have been used while as i think three pins are needed at least-Vcc,Gnd and Tx. So, i need to know it urently what special module is this and what pin is connected to what??
Thank You
you just read the datasheet of the module u have and find out how it works
different moudles have different specs and working
