Hack an Amazon Dash button to work as a wifi doorbell. Shared by initialstate on GitHub:
Constantly looking out the window so that you can intercept visitors before they ring the doorbell? Tired of the dogs and baby going crazy anytime it rings? Don’t want to spend a fortune on a “smart” solution?
Making a silent doorbell is as easy as hacking a $5 Amazon Dash Button! The only other thing you need is a computer that’s always at home – like, say, that Raspberry Pi you’ve got sitting around. Get text notifications anytime someone pushes your new doorbell and keep the whole house happy. (It’s even cooler to get notifications if you have a smartwatch!)
For this project you’ll need:
An Amazon Dash Button
A computer that stays at home (like a Raspberry Pi)

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.
