All scripts dived into here will display decoded QR data live, one will also capture the information into a text file and the final will use specific QR codes to control the GPIO.

Open-CV is a huge resource that helps solve real-time computer vision and image processing problems. To install it and the other required packages it is best done by typing and entering the above 5 lines into the Raspberry Pi Terminal. This guide focuses on QR (Quick Response) Codes. These are absolutely everywhere in our modern world and for great reason. Sharing a lot of similarities to barcodes, but instead of a laser, a camera is used to identify spaces between black and white squares markings. Encoding data this way is incredibly useful and, with machine learning, it has never been easier to decode their secrets. There are lots of standards and types of QR codes but this system will work with all common types.
