QRduino - Sketch to generate/display QRCodes on Arduino

This is a simple sketch that has the following functionality:

1-Waits for the user to input a string (max of 216 characters) through the Serial Monitor
2-Builds the corresponding QRCode by sending an API request, through the Internet, to www.esponce.com.
3-The response is shown as “text” on the Serial Monitor and as a readable QRCode on the display.

Hope it helps…

Best!

Can you tell me what hardware is needed?

Just the Ethernet shield to be able to connect to the Internet and the Display to show the QRCode.
