Learn how to use RFID NFC RC522 with ESP8266, how to connect RFID-RC522 module to ESP8266, how to code for RFID/NFC, how to program ESP8266 step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with ESP8266.

In this Instructable I will show how to control a main socket using a 433mhz transmitter and receiver. I started this project because I wanted to be able to switch my lamp on and off without using the remote that I already had for switching the mains sockets.

/* ESP8266 Receiver Code For 315MHz And 433MHz Wiring ESP Receiver 3.3V = VCC GND = GND D3 = Data */ #include <RCSwitch.h> RCSwitch mySwitch = RCSwitch(); void setup() { Serial.begin(9600); mySwitch.enableReceive(0); // Connect To GPIO0 (D3) On The ESP } void loop() { int value = mySwitch.getReceivedValue(); if (mySwitch.available()) { Serial ...

This is a sketch for controlling RF remote control sockets or relays that operate at the 433MHz frequency and are compatible with the Arduino/esp8266 RCSwitch libraries. The main feature is that you can schedule events (up to 10) to turn ON/OFF your devices that repeat daily/weekly or that actuate once only within a week from setting the command.

2020年3月29日 · The steps below will show you how to control 433MHz sockets with a NodeMCU (with an ESP8266 Wi-Fi chip). I’m currently using this to turn my lights on and off. In this guide I will also cover...

2025年1月13日 · One gateway, many technologies: MQTT gateway for ESP8266 or ESP32 with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, LoRa, beacons detection, mi flora / mi jia / LYWSD02/ Mi Scale compatibility, SMS & LORA.

Control your RF Switches with Amazons Alexa or any browser. Code for a ESP8266 (NodeMCU) based 433MHz RF code sender and receiver. I recommend to use a WL101-341 board, powered by 5V to avoid range issues.

2023年5月29日 · In this tutorial we will learn how to make wireless communication between Arduino board and NodeMCU ESP8266 using the NRF24L01 transceiver module. We will upload the received data on Thingspeak Server. The NRF24L01 can receive data up to 100m distance whereas we can monitor data worldwide using NodeMCU.

In this example we will connect an RFID-RC522 module and connect to a Wemos Mini. The microcontroller and card reader uses SPI for communication . The card reader and the tags communicate using a 13.56MHz electromagnetic field. (ISO 14443A standart tags) Features: Datasheet for the chip that used in modules can be found at:

2021年5月3日 · In this tutorial, we will see the management of an RC522 RFID module with a NodeMCU ESP8266 card. Prerequisite: Program your NodeMCU with Arduino. The RC522 RFID module uses the SPI protocol to communicate with the ESP8266. The SPI communication uses specific boxes on this type of microcontroller.
