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 ...

This tutorial shows how to establish a basic RF communication link using cost effective wireless modules (434 MHz transmitter and receiver). The use of low-cost RF modules could be practical in ...

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 be used with almost all microcontrollers for a ...

We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are identical to concepts used in cell phones and Wi-Fi. Initially we ...

In the transmitter we have connected a push button with a resistor in series and, for the receiver we have connected a LED on the Data line, and both the circuits are powered by a 3.7V lithium battery ...

I use tasmota with ir led and receiver to control my projector with home automation. It works but it is difficult to get it working with 100% certainity even if the transmitter led is 20 cm away ...

It has an RF front end for up and down-link , ... ATA8520 is a transmitter-only version of the same IC that works from 1.9 to 3.6V. Crypto engine: No: ... ATA8520-EK2-E extension board is designed for ...
