We’ve done it with Arduino, and now we did it again with Raspberry Pi. That’s right, introducing the Raspberry Pi-Powered Future House!
Running on a Raspberry Pi Model B+, the house boasts seven embedded LEDs, a couple of sensors to measure humidity, barometric pressure, and temperature, and a stepper motor that remotely opens and closes the door.
The house is figuratively glued together using PubNub, allowing us to publish messages into the house to request on-demand readings from the sensors. Additionally, PubNub powers the remote configuration for the smart home, enabling users to trigger the LEDs and control the front door. We can also request the current state of the house, including voltage and intensity levels.
But the most valuable part of the Raspberry Pi-Controlled smart home is its showcase of the missing link in a lot of IoT applications and projects; powering an easy way to stream data in and out of an embedded device.
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.
