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 ...

In this project, we will build a remote-controlled Arduino Air-Boat that can be controlled wirelessly using the 433 MHz RF Radio Modules.We will control this boat using a homemade remote control by ...

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 ...

"For flea power, we can do the same thing with a transistor, either bipolar or FET," he explained. "All we need then is a crystal-controlled RF signal on the appropriate frequency." AM Transmitter ...

The receiver and motor driver circuit (Fig. 3) is built around Arduino UNO board (BOARD1), decoder IC HT12D (IC2), 433MHz RF receiver module (RX1), motor driver IC L293D (IC3), regulator IC 7805 (IC4) ...

With this circuit, a single transmitter and simple set of user pushbuttons can initiate one of four different outputs, two at each of two remote receivers with very different applications. The ...
