Description

If you own several badges, cards, or tickets and would like to automatically publish the number of unused badges on the web in real-time, there is no off-the-shelf solution. However, with 3D printing, the AVR-IoT Cellular Mini board, APDS9930 proximity sensors, and a bit of Arduino programming, one can come up with a robust and secure solution. Although it does not sound overly complex, I still had to spend a few working days with 3D design, making myself familiar with the board, and come up with the necessary set of scripts and sketches.
