IoT Projects
A Simple IoT Doorbell Camera
Build a simple IoT doorbell camera using Adafruit’s MEMENTO. Press a mini LED arcade button to snap a photo and display it on an Adafruit IO Dashboard. Photos from the doorbell are sent to your email, too! The electronics are housed in a 3D-printed snap-fit enclosure. – Adafruit Learning System
Industrial Network Playground
A “playground” to learn more about hardware and software components in industrial setups, without the need for accessing a real industrial network. – HackADay.io
IOT Squirrel House
In many parts of the world, if you have a backyard, you likely have a bunch of squirrel neighbors, and should probably just make the most of it. Maker David McDaid did just that (and more) when he built this charming IOT Squirrel House for his back garden: “a squirrel house in our back garden that would be equipped with an ESP32, a camera, motion sensor, solar power, and would integrate with my Home Assistant OS, all using as many off-the-shelf components as possible”. – Adafruit Blog
Fixing a broken smart cat feeder with ESP8266
Jeff Sandberg’s PetNet eventually stopped working because the company went out of business. This writeup covers disassembling the cat feeder, reverse engineering it, and using a custom web interface to replace the original app. – PDX.su
Replacing an Old Honeywell Thermostat with a Raspberry Pi
A DIY approach to upgrading an old mercury-based thermostat to a mesh networked system of thermometers that report to a central thermostat. – Hackster.io
IoT News and More!
We want your feedback about Adafruit IO (and WipperSnapper firmware) to help us plan 2024 (and beyond) 🚀
Inspired by Scott’s blog post, CircuitPython 2024, the developers and designers on our IoT Platform, Adafruit IO, are requesting feedback (from you!) to help guide our development of this platform in 2024.
If you’re a current Adafruit Free IO user, an Adafruit IO Plus (paid) user, or have previously used Adafruit IO in the last year, we want to hear from you!
Evan Grove details the process of designing a smart home from scratch after they read a “fair share of terrible, horrible, no-good, very bad news about consumer IoT products bricking themselves and/or pwning their human caretakers. I use the term “caretakers” because you don’t actually own most of these products.” The system they’re designing considers the ethical implications of which gadgets you bring into your home and starts designing a platform. – hardfault.life
Hacking a Smart Home Device
An intense case study on reverse engineering an IoT smart device and the associated network protocol it uses. –jmswrnr
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
