“The project is about designing the 433MHz radio frequency transmitter module that can be used to transmit radio frequencies.
Introduction
Two devices can communicate with each other using radio frequencies and using an RF transmitter is one of the simplest ways to do it. Various compatible ranges within the RF communication system range from 30 kHz to 300 GHz. The communication system’s digital data is constituted as disparities within the carrier wave’s amplitude; thus, the representation and modulation are referred to as the Amplitude Shifting Key (ASK).
Conceptualization of the Project
To conceptualize the 433 MHz RF Transmitter, a four-push button switch in an RF wireless medium will be used to control the 4 LEDs. The four push buttons are attached to an IC encoder. The primary function of the IC encoder is to get 4-bit data from each of the four push buttons and later transform it into serial data. The IC encoder also transmits the acquired 4-bit data with the help of an RF transmitter.

Components
A 433 MHz RF Transmitter, an HT12D encoder IC, four push buttons, LEDs, Jumper wires, an Arduino board, a 7805 Voltage Regulator, ohm Resistors, a Ceramic Capacitor, and a 9V battery that has a battery cap.
The tools used to attach the components include a soldering Iron, wire, flux, stand, wire cutter, multi-meter, and a de-soldering pump.”
