hi everyone. I using arduino uno and met troubler when using rfid library. According to rfid library manual, pinn13 in arduino should be connected to pin sdk in rfid reader. But for some reason, i want sdk pin and pin 5 hooked up together. So can anybody help me. Should i change something in rfid library??? P/s: i am using rc522 reader and library rfid-master( you can find it by google)
