IrOn-Off


IrOn Off


Turn ON or OFF electrical devices using remote control is
not a new idea and you can find so many different devices
doing that very well. For realization of this type of
device, you must make a receiver, a transmitter and
understand their way of communication.


Here you will have a chance to make that device, but you
will need to make only the receiver, because your
transmitter will be the remote controller of your tv, or
video …This is one simple example of this kind of device,
and I will call it IrOn-Off or Ir-switch.


How it works



Choose one key on your remote controller (from tv,
video or similar), memorized it following a simple
procedure and with that key you will able to turn ON
or OFF any electrical device you wish. So, with
every short press of that key, you change the state
of relay in receiver (Ir-switch).

Memorizing remote controller key is simple and you can do it
following this procedure: press key on Ir-switch and led-diode
will turn ON. Now you can release key on Ir-switch, and press
key on your remote controller. If you do that, led-diode will
blink, and your memorizing process is finished.


Instructions



To make this device will be no problem even for
beginners in electronic, because it is a simple
device and uses only a few components. On schematic
you can see that you need microcontroller PIC12F629,
ir-receiver TSOP1738 (it can be any type of receiver
TSOP or SFH) and for relay you can use any type of
relay with 12V coil.

Program code for this device is used from IrLightDimmer and it’s
only a subroutine, which is used for memorize and recognize ir-protocol.

I hope you will find a place to use
this simple and usable device.
