cybiko:relaycontrol [2009/11/27 17:54] (current) – created - external edit 127.0.0.1
Line 1: Line 1:
 +======Overview=======
  
 +The relay control program allows remote control of an AVR relay block.\\
 +It does this by sending a string that can be interpretted by the AVR microcontroller board to a remote cybiko that is connected to the RS232 port of the AVR.
 +
 +The project would be similar to that done with a GSM phone except that a Cybiko would  be in its place.  See worked up [[http://www.dbzoo.com/hw/smsrelay/index.html|GSM Solution]]
 +
 +======Comments======
 +
 +  - Assumes that the relay board has an initial state of all OFF 
 +  - Needs to handle the fact that the AVR board states and the Cybiko program can get out of sync, if either is reset independantly.  The introduction of a status command that will return the state of all relays would help solve this (and also the assumption in point 1, above.).
