In this Arduino tutorial we will learn how to make a wireless communication between two
Arduino boards using the NRF24L01 transceiver module. You can watch the following
video or read the written tutorial below.
Overview
For explaining the wireless communication we will make two examples, the first one will be
sending a simple “Hello World” message from one Arduino to another, and in the second
example we will have a bi-directional communication between the Arduino boards, where
using the Joystick at the first Arduino we will control the servo motor at the second
Arduino, and vice versa, using the push button at the second Arduino we will control the
LED at the first Arduino.
NRF24L01 Transceiver Module
Let’s take a closer look at the NRF24L01 transceiver module. It uses the 2.4 GHz band
and it can operate with baud rates from 250 kbps up to 2 Mbps. If used in open space and
with lower baud rate its range can reach up to 100 meters.
