Wifly automatic home control - using Telnet anywhere with home router address
The commands are
c1 activate GPIO4 to '1'
c0 deactive GPIO4 to '0'
c2 unlocked for 3 minuets without feedback after locked
rr read status of gpio4
r0 reset internal counter to zero
//PINS in USE are:
//D4 - relay command
//A4 - RTC DATA
//A5 - RTC CLK
//D6 - Reset pin to Wifly (to Wifly pin 5)
//D10 - RX WIFLY (TX)
//D11 - TX WIFLY (RX)
//
//need to connect resistor in series to change from 5V to 3.3V
//suggest 1K, 2.2K while 2.2K to GND and 1K to D10,D11
//
//
//
// using timer library from NET
//https://github.com/JChristensen/Timer
//to add it goto Sketch-> import library -> add librarry -> choose the ZIP file
//
//april 2015 - adding I2C RTC
//on NANO A4=DATA, A5=CLK
//another library for RTC:
//RTC DS1307RTC

This Program is doing automatic on/off randomly, all you have to do is set the number of switch that you have and the time limits (start time and stop time) – between those times, it will automatically control the lights.
This uses the following:
Arduino Uno board
RTC DS1307 board – real time clock
Transmitter of 433Mhz
