arduino with RFID and LCD project overview in tamil

-


this is the simple projec for arduino with RFID and LCD display... here the name of student only displayed in LCD display.... we can sent that to cloud to online attendance using esp8266 or using lab with python....

                                 The code is here

/*

copy that and paste in the arduino IDE and then upload that..... connections are given there(in codings)....
