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
