Esp32 rfid examplelavori
Il mio progetto consiste nel controllare tramite un modulo ESP32 DEVKIT V1 un motore brushless. Sul modulo ESP32 ci sono montati due pulsanti, uno sul pin 18 per aumentare la velocità del motore, l'altro sul pin 19 per diminuire la velocità del motore. Il motore è collegato ad un ESC il quale è collegato tramite il pin 9 ad una arduino UNO. Sulla arduino UNO è inoltre montato (pin RX e TX) un modulo HC-06 (indirizzo mac: 98:D3:31:FD:2D:B5 , pin: "1234"). Obbiettivo è quello di avere i codici (uno per ESP32 e l'altro per Arduino UNO) che mi permettano di collegare l'ESP32 all'HC-06, di poter inviare segnali di aumento e diminuzione di velocità al motore. Nella posizione iniziale il motore dov...

Abbiamo bisogno di implementare un nostro progetto con un impianto di ricarica. Un Arduino è collegato al modulo NFC RFID PN532 che legge una tessera con credito ed avvia una pompa. Mentre avviene la ricarica, il misuratore di portata d'acqua YF-S201 legge i litri che passano e scala il credito dalla tessera. Quando si esaurisce il credito, perché sono passati tutti i litri autorizzati, la pompa si spegne e la scheda viene "bruciata" in modo che non sia più utilizzabile.

We have around 80 ESP32 based wireless devices in a center. These devices communicate with our local server which is assigned a static IP. We have a live TCP socket from each of the device to local server. This socket reattempts connection if device doesnt hear from server for 20sec. Everything runs smoothly for a period of time and then suddenly devices start disconnecting and reconnecting to this TCP socket. This goes on for around 1hr or so and then most of the time situation self resolves. If we restart the access point/router we see improvement in the situation but it does recur. During the period of 'reconnections' even HTTP requests from devices to server start to fail. Pings from server to device IP times out too. We can see in access point that the device is stil...
