USB power outlet – Or could use a Pi power adapter if you have a power outlet at the doorbell
Small USB to micro USB cable
Small proto board to solder connections
2 – 10k resisters
5 jumper cables
The installation will have to be customized to your existing doorbell system. I was hoping for a 3D printed Doorbell box I could print out at the local Makerspace, but I couldn’t find any suitable plans and have yet to learn how to make my own.
I used a reciprocating saw to cut open the sound chambers in the old doorbell housing and put in the speakers. The Pi Zero just stays in place with the micro USB power cable. I put a little tape to keep my circuit board in place. I striped the ends of the yellow leads from my circuit board and twisted together the bare copper wires with the wires from the doorbell button. My Doorbell button wire is blue and white-blue Cat 3. I covered the bare copper with electrical tape.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
