Difficulty level: beginner. 1 x Arduino Uno R3; 1 x RWS-371 RF Receiver Module (434 MHz); Breadboard + wires. Note. RF modules (transmitter and receiver) at other frequencies (i.e. 315 MHz) could be ...

Connect this to a voltmeter on DC and hold the loop close to the rf transmitter. You should see a hundred millivolts if it is transmitting. Circuit diagram for this Arduino transmitter and receiver is ...

The transmitter module consists of three pins that is VCC, Data and GND. The VCC pin has a wide range input voltage from 3V to 12V. The transmitter consumes a minimum current of 9mA and can go as high ...

These days, 433-MHz RF transmitter/receiver modules are very popular ... As you can see, the setup is on the Arduino ground with a 433-MHz receiver module and the USB interface. The code to capture ...

The project also makes use of Arduino Nano as microcontroller (MCU) and 433MHz ASK RF transmitter module. There can be many such sensor nodes but only two such nodes are used here. The receiver ...

and the ground pin of the transmitter module is grounded. In here I used a breadboard for connecting the modules, and a push-button is used as a doorbell switch. Similarly, on the receiver side, we ...

2) is built around encoder IC HT12E (IC1), 433MHz RF transmitter module (TX1) and a few discrete components. The receiver and motor driver circuit (Fig. 3) is built around Arduino UNO board (BOARD1), ...

We haven’t included the RF transmitter in our circuit diagram because we ... Find a stick at your home and attach the circuit comprising of Arduino and RF receiver on it. You can use Hot glue gun for ...
