RFID Shield and LCD

Post by TheGiwiNinja »

HI. Im an amateur arduino user who needs some help. Collin cunningham has a Collins lab episode where he uses the RFID shield from adafruit in conjunction with an LCD shield to display the RFID tag data. Ive looked everywhere and ive also asked around at the "Ask an engineer" on wednesday nights and i cant find anything that shows how to make those two shields work together like collins did. I want to create a setup that will allow me to scan and show RFID data tags using the lcd shield and RFID shield, without using my computer, just with a 9v power brick that plugs into the arduino.

Thanks

The LCD shield uses address 0x20 and the RFID shield uses address 0x48 so they will both connect to the i2c pins (A4, A5) on the Arduino and you write code for them just like the other one was not there.
