"Radio is powerful not because of the microphones, but the one who sits behind the microphones."
- Ernest Agyemang Yeboah
In this chapter, we will learn different techniques for performing short range wireless communications using the Arduino platform with radio frequency (RF) technology. It is generally perceived that radio waves can travel very long distances, which is true. However, there are different types of radio waves. Some radio waves travel across the globe and beyond this planet, while some can travel only a few hundred meters.
As we read through this interesting chapter, we will discover how to use some popular RF transceiver chips for sending and receiving radio waves.
You will learn the following topics in this chapter:
- Building an RF device
- Using the nRF24L01 2.4 GHz ISM band RF transceiver chip with Arduino...
