RF(Radio Frequency) based wireless data communication-Tutorial in Bangla

This video explores an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules that are readily available in the market. They are found in different shapes, but functionally they are all same. Both Tx and Rx modules contain a single data line for input and output and support a low-speed Amplitude Shift Keying modulation for data communication. You can get them with 315MHz or 433MHz carrier frequency. In this tutorial, I am using a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless data communication between Two Arduino boards. I am using an Arduino Nano on transmitting side and Arduino Uno on receiving end.The transmitter module has four pins: VCC, Data, and Gnd, antenna. They could be in different sequence depending upon the manufacturers. So, always read the pin labels carefully to identify the data and power supply pins on these modules. The VCC and Gnd pins are connected to +5V and Gnd pins of Arduino Nano, whereas the Data pin of the Tx module goes to digital I/O pin 12 of Arduino. An LED is also connected to I/O pin 11 along with a current limiting resistor in series.

What is the range of RF?
Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting.
What are RF fundamentals?
This video will be discussing Radio Frequency Fundamentals. Very basically, Wi-Fi is made up of stations that transmit and receive data. Wireless transmissions are made up of radio frequency signals, or RF signals, which travel using a variety of movement behaviors (also called propagation behaviors).
How is RF generated?
Radio frequency waves (RF) are generated when an alternating current goes through a conductive material. Waves are characterized by their frequency and length. ... Radio waves are electromagnetic waves and they travel at the speed of light in free space
What is RF testing?
RF Testing Definition/Description: RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.
