rboard - Cheap relay/radio/arduino board ~$10
-
Nice find. Please let us now how they perform.
-
Finally got the email they are on the way....will report in when ive tested them,
-
And they just arrived... 6days ..not too bad!
Now to test!
-
Well that was easy....
Loaded up the RelayActuator sketch, changed the relay pin to 4.
It joined Vera as it should, and after providing it a 5V powersource the relay clicks on and off as commanded! -
Now loaded up the Garage Door sketch , choosing A0 for the switch and D4 for the relay and again works straight away!
I note they also have a header for 433Mhz module and according to the schematic, the pads could be used for 5v,GND, and D3 - so could be used for another sensor such as Dallas temp....or ultrasonic/IR..anything!
Great buy for $10

Good price but a pity you still need an external 5 Volts supply...
-
Yep no getting away from the need for power! A mains version would be great, but although it only adds a few $ in electronics, getting all the approvals adds $$$. But for DIY'ers adding a phone powersupply is cheap and reasonably compact.

Yeah it seems like a really nice board but it could have had access to a few more digital pins on the board.
Is it really only A0 and D3 that can be accessed other then the relay? -

Which board do I choose when uploading a sketch to this?
It's all good, I found a website which stated what it was compatible with So I'm moving on :-)
Now I am just trying to work out how to connect a switch to the A0 pin. There are two pins so is the switch just bridging the two? Sorry, I really am trying to learn this stuff.

Ok, looks like I am slowly getting there :-)
fyi I tried playing around with the above sketch, but it's a no go as Codebender tells me <Bounce2.h> is missing.
