These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

This project demonstrates wireless data transmission using a Raspberry Pi Pico (transmitter) and Arduino Uno (receiver) over low-cost 433 MHz RF modules. Messages are encoded bit-by-bit on the Pico in ...

I wanted to begin with the fundamentals. In that case, I learnt how to use an Arduino to transmit data using the nRF24L01 module. Afterwards, a potentiometer attached to the transmitter was used to ...

I use tasmota with ir led and receiver to control my projector with home automation. It works but it is difficult to get it working with 100% certainity even if the transmitter led is 20 cm away ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals.

The RF transmitter and receiver units are the two main components of the system. In this configuration, RF signals including information on the speed limit are broadcast by the transmitter unit, which ...
