While Matter, Bluetooth, Zigbee, and Zwave may get all the press these days, 433 MHz was the simple yet reliable technology that our sensors and devices relied on before they became popular. Given the wide range of applications for the 433 MHz, generalizations regarding the technology are likely to be oversimplified. Numerous household and automotive […]
Using the 433MHz RF Transmitter and Receiver with Arduino
https://www.electronics-lab.com/using-433mhz-rf-transmitter-receiver-arduino/
While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive). Several options […]
ANTENNINO – Arduino-RF multifunction board
https://www.electronics-lab.com/antennino-arduino-rf-multifunction-board/
Antennino (the name Antennino is the combination of Antenna and Arduino) is a low-cost and low-power board based on the Atmel chip, then 100% compatible with the traditional Arduino IDE. The board integrates sensors and bus communication to get external information, as well as a wireless link to communicate with the outside. <span title=”A seconda […]

Dire situations require unpleasant solutions, an excellent example of this statement is spying and we have seen what the NSA has done in this regard. It goes against proper ethical character, however, it might be needed in certain circumstances. Usually, the first thing a person who wants to spy would do would be to check […]
Arduino 433Mhz RF Wireless Data Transfer
https://www.electronics-lab.com/arduino-433mhz-rf-wireless-data-transfer-2/
runtimeprojects.com has a tutorial on how to use 433Mhz modules to communicate between 2 Arduinos. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in […]
