Solar Power Gauge


When Ben and his wife got solar this past winter, they wanted to know how much power they generated (especially as they moved closer to the equinox). This meter was built as an experiment to measure the power output of their home’s solar system. -

Stuff My Dog Said


This fun project is a web-based dashboard that displays the latest messages from a dog. A dog. The dog presses their paw down on a specific button on a floor mat to use it. The mat translates the button press into a specific phrase, uses a speaker to “say” the phrase, and publishes the phrase to a web dashboard on Adafruit.IO - Adafruit Playground

An Internet-Enabled 3D Printer Filament Sensor


This 3D printer sensor can detect (and notify you) when the filament is about to run out by measuring the diameter of the filament. -

E-Ink Status Dashboard for a Car


A wood-enclosed e-ink dashboard for a car that displays the current mileage, battery level, gas level and inside temperature. -

Post-Apocalyptic Home Automation Terminal


This Raspberry Pi 400-based post-apocalyptic terminal to run a home automation system looks like a prop from the Fallout TV show. The case around the Raspberry Pi 400 was specifically crafted to look like it came from a post-apocalyptic world. -

Insights: IoT market to More than Double in 10 Years


A study by Transforma Insights found the “number of active IoT devices will more than double to 40 billion by the end of 2033”. While this is not a “hockey stick growth” trend, it’s steady. - RCRWireless

Desk of Ladyada – Desk plant health monitoring with SproutSense and


On this episode of Desk of Ladyada, we’re getting green and experimenting with soil moisture sensing on a prototype we’re testing out called SproutSense. Right now we’re trying to figure out: why does the capacitance slooowly rise over the course of days, and how can we detect when the soil has dried out using some sort of logic/hysteresis since the depth of the sensor can affect the absolute value. We also talk about sending serial output data to Adafruit IO for monitoring. - Adafruit Blog

Support Adafruit


Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
