In this video, we show you how to make a smartphone-controlled, internet-connected deadbolt actuator powered by a Raspberry Pi that can be added onto your existing door lock without any modifications to the door. The door lock can be controlled by multiple smartphones, and even notify you whenever someone locks/unlocks the door. All of this is done using a simple, drag-and-drop app builder (http://www.blynk.cc/) which makes building your own Internet of Things (IoT) app easier than ever. For an extra impressive door lock, we’ll also show you how to add a simple LED light to indicate if the door is locked, and a push-button to operate the lock manually.

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.
