The transmitter part consists of Arduino UNO and the 434 MHz Transmitter module. An external LED can be used but on board LED would be sufficient. The design of the Transmitter part is as follows. The ...

The code implements a minimalist RF communication link between the two microcontrollers. It uses the RadioHead-1.74 library and is basically a slight variation of the original example code (included ...

They can either be used as standalone Transmitter and Receiver or be interfaced with a MCU/MPU like Arduino or Raspberry Pi. Here we will learn the basics of RF module and how to use it as a ...

Here at RF Transmitter side, we have used Arduino Nano. Wiring the receiver module is also very simple, and once again you only need to make three connections. Connect the modules VCC and ground pins ...

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can. ... Arduino code /* -Arduino 433MHz RF Sniffer ...

Step 4: Assembling The Circuit. We will need to design two circuits for this project. The first circuit will be placed at a suitable place in a blind man’s stick and the second one will be an RF ...

Presented here is a RF controlled aircraft project based on Arduino and 433MHz RF modules controlling a brushless DC motor and three servo motors. It comprises an Arduino-based remote control at the ...
