This project demonstrates how to build a color sensor detector using the APDS-9960 and the Adafruit Feather ESP32-S2 TFT (you can also use Adafruit Feather ESP32-S3 TFT) to control HomeKit devices through ItsaSNAP.

This example uses a Nanoleaf light strip to display the detected colors, but this method works with any HomeKit-compatible light capable of showing colors. itsaSNAP acts as a bridge between Adafruit IO feeds and HomeKit devices, allowing updates to HomeKit accessories based on sensor input—all without writing a single line of code.

What is itsaSNAP

itsaSNAP is a simple iOS app that explores Adafruit IO. It lets you send data to your Adafruit IO feeds and link it to control or monitor your internet-connected projects. We recently added HomeKit functionality. You can now send Adafruit IO data to HomeKit devices. This lets you control and check Adafruit devices from your phone, anywhere.
