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) ...

Control Any Circuit with a TV Remote and an Arduino. Walter Glenn March 27, 2014 ...

To build your Arduino RF Remote Joystick you can follow the below Circuit Diagram. The RF Joystick circuit can be powered using the USB port of the nano board. The nRF24L01 module operates only on ...

By using this device we can save more time in searching for Remote, for buying the Batteries, by focusing Remote exactly to TV for changing, etc., for this no need of any external power supply, ...
