I have little experience with arduino and now i have project with RFID. I want to make the program record data sensor if i tap the RFID and stop record the data if i tap again the RFID. Could you give me some ideas what should i do??
You start with basic wiring diagram. Intially you use RFID working & make use of Serial print to check its working.
Once RFID worked then use Internal EEPROM/External eeprom to save data. Use Read and write function to save data
What sort of data do you want to record? An Arduino has very little SRAM.
Assuming an Arduino is suitable then start with a short program that detects the RID tag and displays some info on the Arduino serial monitor. Google should find you lots of examples.
