Get a beta invite to Adafruit.io WipperSnapper

Wippersnapper is a new no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming. Simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create an IO feed for visualization.

How can I get an invite to the Adafruit.io WipperSnapper Beta?

First – You’ll need a compatible board to use with WipperSnapper. WipperSnapper currently supports the following hardware: Metro ESP32S2, FunHouse ESP32-S2, MagTag ESP32S2, PyPortal, Metro SAMD51+AirLift.

Then – Navigate to the official Adafruit Discord Server and post in #help-with-adafruit-io that you’d like a WipperSnapper beta invite. We’ll message you over Discord with further instructions!

Sneak Peek of Adafruit.IO Wippersnapper – Analog inputs working!

Wippersnapper is our upcoming no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming – simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create a IO feed you can then log and/or use to control other devices by triggering events or webhooks. We recently added analog inputs, and wanted to show off how it works with selecting an element (potentiometer) and the attached analog input pin, to getting it in as an MQTT feed…all in just about 1 minute! - Adafruit Blog
