PebblyPi Smart Doorbell Tutorial @Raspberry_pi #piday #raspberrypi

Metal16mmbuttons

Due to popular demand, Daniel Garden has put together a tutorial for his PebblyPi Smart Doorbell project. Check it out here!

Wire and Mount Your Button

The button I chose had both a normally open and normally closed setup. As I want to pull the button low to activate the python code I soldered the ‘NO1′ to the ‘Blue+White Stripes’ wire and the ‘C1′ to the ‘White+Blue Stripes’ wire. I also want to power the LED so soldered the ‘+’ to the ‘Orange+White Stripes’ wire and the ‘-’ to the ‘White+Orange Stripes” wire. Honestly, the wiring layout doesn’t matter just make sure you note down what wire is what before you permanently mount the button.

I used the laser cutter at Makespace in Cambridge to make a nice mounting plate for the button and mounted it on the outside of my house with wall plugs. Snazzy huh?

Raspberry Pi & Pushover – Software and Wiring
The current build of raspbian has the EDIMAX drivers included as standard. However if you are using a distro without these drivers, Robert Savage has a good tutorial on how to use the EDIMAX wifi adapter.Now download the Pushover App, make sure you can send notifications to your pebble (see this entry in the Pushover FAQ for help) and login at http://pushover.net. Create a new application by clicking ‘Register an Application’.

Adafruit Prototyping Pi Plate Kit for Raspberry Pi: Now that you’ve finally got your hands on a Raspberry Pi® , you’re probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Plate from Adafruit, which can snap onto the Pi PCB (and is removable later if you wish) and gives you all sorts of prototyping goodness to make building on top of the Pi super easy.

We added lots of basic but essential goodies. First up, there’s a big prototyping area, half of which is ‘breadboard’ style and half of which is ‘perfboard’ style so you can wire up DIP chips, sensors, and the like. Along the edges of the proto area, all the GPIO/I2C/SPI and power pins are broken out to 0.1″ stips so you can easily connect to them. On the edges of the prototyping area, all of the breakout pins are also connected to labeled 3.5mm screw-terminal blocks. This makes it easy to semi-permanently wire in sensors, LEDs, etc. There’s also a 4-block terminal block broken out to 0.1″ pads for general non-GPIO wiring. Finally, we had a little space remaining over the metal connectors so we put in an SOIC surface mount chip breakout area, for those chips that dont come in DIP format. Read More!
