Wireless Remote Doorbell : Bluetooth Wireless Print Adapter
Wireless Remote Doorbell
- A remote control unit that uses either IR (infra-red) or RF (radio frequency) signals to control another device (think of your TV or cable remote).
- A doorbell is a signaling device typically placed near a door. Most doorbells emit a ringing sound to alert the occupant of the building to a visitor's presence, when the visitor presses a button. Many modern doorbells are electric — they are actuated by an electric switch.
- Il campanello or Il campanello di notte (The Night Bell) is a melodramma giocoso, or opera, in one act by Gaetano Donizetti. The composer wrote the Italian libretto after Mathieu-Barthelemy Troin Brunswick and Victor Lherie's French vaudeville La sonnette de nuit. The premiere was on June 1, 1836.
- A bell in a building that can be rung by visitors outside to signal their arrival
- a push button at an outer door that gives a ringing or buzzing signal when pushed
Xbee to Xbee using Direct IO ( DIO )
I spent some hours trying to make two xbee wireless
communicate. These will be part of our new flaming doorbell
trouble was with my transistor setup for the relay. The modules were
communicating, but the logic was backwards and each time I hit a
button the relay would turn off. I need the opposite behavior
otherwise their would be a 20' flame at all time at our place. I
finally gave up on trying to convince the xbee modules to behave
rationally and just switched to a PNP transistor for the relay.
The configuration for both xbee modules is straight forward (thanks
ladyada for documenting this):
Remote - TX setup (attached to doorbell input button)
- D0 - DIO Configuration - (3 - DI) [data in]
- IC - Dio Change Detect - (FF)
- Set sample rate to 0 (unless you want synchronous updates)
Base - RX setup
- DO - DIO Configuration - (4 DO) [data out low]
- Under I/O Line Passing set "Input Addresses" to 0xFFFF (allow any
- Set IU - I/O Output enable to Disabled
Canon Wireless Remote
Last week I was doing some online shopping and I came across this wireless remote
(that I had been looking for a while) on amazon.com and it was only $9.99. I haven't had the chance to test it out fully, so I'm definitely am going to do that today. So expect a few SP.
This isn't the shot I'm using for Bokeh Wednesday
but it's a little in the picture.
