Hello Everyone! I designed, built and coded this Raspberry Pi & Arduino based project for my Humber College ATMN 256 Second Year Project Course utilizing Python3 and the Pi for the main control system to have a automated project.
I developed a small scale industrial product sorter utilizing RFID tags for product data, a belt conveyor for transporting it (Build for last years project) along with IR through-beam sensors for position tracking. To finish it off, I have a 4 DOF robotic arm with suction to pick and place the product into drop-off containers.
Tried to build everything somewhat "professional" utilizing DIN Rail power supplies and terminal/distribution blocks to keep some of the wiring tidy.
In trying to make a wifi repeater/extender using the esp32 board I tried the same with esp8266 and it worked quite well but I'm having problems to understand the same with esp32 I found the esp8266 code in official arduino examples ie: `ino // NAPT example released to public domain #if LWIP_FEATURES && !LWIP_IPV6 #define HAVE_NETDUMP 0 #ifndef STASSID #define STASSID "mynetwork" #define STAPSK "mynetworkpassword" #endif #include <ESP8266WiFi.h> #include <lwip/napt.h> #include <lwip/dns.h> #define NAPT 1000 #define NAPT_PORT 10 #if HAVE_NETDUMP #include <NetDump.h> void dump(int netif_idx, const char* data, size_t len, int out, int success) { (void)success; Serial.print(out ?

"Hello and welcome to this tutorial where we'll be exploring how to use an RFID-RC522 module with an Arduino to control an LED. This is a fantastic project for beginners looking to delve into the world of Arduino and RFID technology."
What You'll Need:
An Arduino Uno (or any other Arduino board) RFID-RC522 Module An LED 220-ohm resistor Breadboard Jumper Wires Step 1: Overview "We will start with a brief overview of the RFID-RC522 module and its functionality. This module operates at 13.56 MHz and communicates over the SPI protocol, making it ideal for projects involving identification."
Step 2: Connections "In this section, we'll go through the process of connecting the RFID-RC522 to the Arduino. We'll attach the SDA, SCK, MOSI, MISO, RST, GND, and 3.3V pins of the RFID module to the corresponding pins on the Arduino. Remember, it's crucial to connect the 3.3V pin to the Arduino's 3.3V output, as the module is not 5V tolerant."
Step 3: LED Setup "Next, we'll connect an LED to the Arduino. We'll use a 220-ohm resistor in series with the LED to protect it from high current. The longer lead of the LED, the anode, will be connected to digital pin 7 of the Arduino, while the shorter lead, the cathode, goes to the ground."
Step 4: Code Explanation "Now, we'll dive into the code. We'll explain how to use the MFRC522 library to interface with the RFID module. The code will be set up to turn the LED on for a few seconds whenever an RFID tag is detected by the module."
Step 5: Demonstration "We'll conclude with a live demonstration of the project. You'll see how, upon bringing an RFID tag close to the reader, the LED lights up, indicating the tag's detection."
Outro: "Thank you for watching! This project is a great starting point for anyone interested in RFID technology and its applications in the world of Arduino. Don't forget to like, share, and subscribe for more exciting projects!"
