In this project, we are using a 434 MHz RF Transmitter – Receiver pair. This module can be used for communication for distances up to 40 meters. Circuit Design Transmitter Part. The transmitter part ...

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 ...

433MHz RF Transmitter and Receiver Module: Let me give brief intro to these RF modules before getting into the project. The term RF stands for “Radio Frequency”. A RF transceiver module will always ...

In here I used a breadboard for connecting the modules, and a push-button is used as a doorbell switch. Arduino RF Receiver Circuit Diagram. Similarly, on the receiver side, we need to use another ...

The antenna switch is an Integrated Circuit (IC) that will connect the antenna to either the transmitter or the receiver based on the logic state of one or two control lines. The switch serves two ...

The transmitter circuit (Fig. 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 ...

Pin details of nRF24L01+ (shown in Fig. 5) and nRF24L01+PA and LNA modules are the same. Fig. 4: Receiver circuit. The nRF24L01+ module is connected to an I2C 64×128 OLED through an ATmega328P. The ...

Wireless Communication in any form has become an essential part of human life whether it may be short distance T.V Remote or long distance radio communication. Wireless communication is all about ...
