I've bought 3 components for my Arduino project:
- SM130 MiFare RFID Module (RFID Module - SM130 MIFARE® (13.56 MHz) - SEN-10126 - SparkFun Electronics)
- RFID Evaluation Shield 13.56 Mhz (SparkFun RFID Evaluation Shield - 13.56MHz - DEV-10406 - SparkFun Electronics)
- Arduino WiFi Shield (Arduino Wi-Fi Shield - DEV-11287 - SparkFun Electronics)
I've got the Arduino (Uno) working fine with both the WiFi shield and the RFID shield separately, but when I stack them both on the Arduino it doesn't work.
Does anyone know why this is, or have any possible solutions?
Thanks in advance!
