    Il progetto prevede una configurazione hardware già definita parzialmente con scheda controller+rfid+wifi+schermo touch oltre a modulo di alimentazione da definire. Il software dovrà prevedere la lettura di card rfid e inviare i dati della card ad un server. I dati sono riferiti ad articoli da ordinare semplicemente avvicinando la card, ogni card corrisponde ad un articolo. Il software dovrà inoltre dare la possibilità di inserire la quantità ordinata dopo la lettura della card e vari messaggi di conferma o errore. Dal lato server i dati dovranno essere ordinati per cliente, articolo, quantità (dati presenti in ogni card) Lo spunto lo prendiamo da questo progetto pubblicato :

    I have a tilting tricycle that performs as a virtual bicycle at speeds above 5mph. Below that it convert to a low tilt vehicle that can dynamic level as it crabs around at this speed compensating for rolling tilting surfaces like driveways and pot holes. I have developed a lock or and drive actuator. I can manually controller. I am using an analog electrolytic tilt sensor used in farm equipment and motor homes to level them. I want to switch to Arduino for better control of functions and debugging.

    It's needed to make the script that will: 1) make a photo each second from connected USB cameras (3 pcs) and save this photo in a specific folder (separate folder for each camera: camera 1, camera 2, camera 3). The name of the photo will be the time of its creation. 2) automatically start with Jetson Nano start and will automatically turn off after an external power cut (I'm using UPS, so we can see external power voltage and battery voltage). Jetson nano must start when external power appears. 3) Video from the camera must be shown on the display. The display must be divided to show video images from each camera. Remote access to the Jetson Nano - AnyDesk.

When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as above ...
