RFID can use in many area such as security systems, door key, etc. Any RFID card have special ID so you must set your Arduino board to identify that ID for work only on your card. You have to follow this steps: 1-Connect your RFID module to Arduino board as follow 2-upload the programming code to Arduino board. 3-open "serial monitor" then put your card near RFID module. 4-you must add the number(ID) that shown in serial monitor to the code and upload the code again. 5-Now when you put your card near RFID module the output be turn on and after 5 seconds the output turn off automatically.(this time can change by change the number that written after "delay" in programming code).  // the sensor communicates using SPI, so include the library: #include <SPI.h> #define uchar unsigned char #define uint unsigned int //?????? #define MAX_LEN 16 ///////////////////////////////////////////////////////////////////// //set the pin //////////////////////////////////////////

This circuit is simplest electronic regulator that can use for fan, lamps or any other dimmable electric devices. It is similar to commercial electronic fan regulators. The triac don't need to heatsink because the ceiling fan consume low power(lower than 100W). Parts list: Triac BT136 Potentiometer 500k (with switch) Diac DB3 Capacitor 0.1uF 400v(3pcs) Resistor 10k Resistor 15K Resistor 100R Coil 40uH NOTE: Don't touch the circuit when it connected to electric line
