This is a re-post of  this blog posting since it appears to be a 404. —- My current project revolves around using the Arduino and the X10 home automation protocol and hardware. The gist of what I am doing with this project is using the Parallax RFID (found here) tag to identify me and then use X10 protocol/hardware (Part# 1134B from SmartHomes via Amazon) to automate my home. Below is the wiring diagram. In this example, I control 1 device (on X10 circuit A, device 1). I initally turn the device off. When the RFID tag I am looking for is read, I turn the lights on. Next time that tag is read, I turn the lights off. I acknowledge various changes by providing feedback to the user via blinking LEDs and serial comms to the PC. I use the free SSH/telnet client PuTTY, found here. Now, for the code… ——————————————– #include x10.h #include x10constants.h // RFID reader variables #define TAG_LEN 12 char tag[12] = {’0′, ‘F’, ’0′, ’3′, ’0′, ’3′, ’7′, ’1′, ’8′, ’5′}; char code[12]; int bytesread = 0; int ledPin = 13; // Connect LED to pin 13 int rfidPin = 2; // RFID enable pin connected to digital pin 2 int val=0; // X10 Control unit variables int zcPin = 9; int dataPin = 8; int repeat = 1; boolean LightsOn = false; // Declare and instance of an X10 control module x10 myHouse = x10(zcPin, dataPin); // 9 is 0xing pin; 8 is data pin … Continue reading →
