DAY C2    

 The second day of the competition was dedicated to embedded system programming. The competition day was again divided into two parts, before and after lunch.

In the morning, the basic part of the Test Project was programmed. The programming tasks are related to the functions of the different modules of the device. 

The programmable device was so ingeniously designed that even after the first section, it was impossible to guess what it would eventually become.

During the author's presentation after lunch, it became clear that the device simulated postal parcel lockers. 

The user interface of the device was buttons or voice control. The compartments were represented by an 8 x 8 RGB LED matrix. The device also print a receipt for the deposit on a Thermal Printer. The printed receipt opened the compartment accordingly.
