## Description

QR codes are a great way for users to communicate with microcontrollers, whether it’s passing WiFi credentials to set up connectivity or sending personal information to fill out a digital badge. Reading them from a maker project didn’t used to be easy though. You’d either needed a large and relatively expensive standalone module, or your own software solution on a board with a camera.

The Tiny Code Reader from Useful Sensors is smaller than a quarter, very low cost, and connects through Qwiic. This makes it the perfect add-on for all kinds of projects that could benefit from text input, but don’t have a keyboard or touch screen. Since QR codes are also easy to share over email, text, or even paper, they can also be used as passwords for access control on security-minded products.

It comes with a [comprehensive developer guide](https://github.com/usefulsensors/tiny_code_reader_docs/blob/main/README.md), which includes example code for popular systems like Arduino, Raspberry Pi, Pico W, CircuitPython, and MicroPython, along with complete project tutorials for Wifi provisioning, keyboard input, and display updating.
