Arduino Uno with Husky Lens using I2C

The HuskyLens is an easy-to-use AI machine vision sensor. It is equipped with multiple functions such as:

• Face recognition
• Object tracking
• Object recognition
• Line trace
• Color recognition
• Tag recognition (QR code).

Via the UART / I2C port you can among others: boards connect:

• Arduino
• micro:bit
• Raspberry Pi

Steps to take: Press Face detection, when a cross in a square is displayed, press the button on your HuskyLens

Set your husky protocol to I2C in the settings.

Minimal Code needed
