What do you need to know about Arduino RF communication?

It will help you get acquainted with using simple RF modules and transmitting sensor data between two arduino boards. In this tutorial, one temperature sensor has been used. However, once you are comfortable with handling RF communication, you can add more and different types of sensors to gather data. For this tutorial, you will need:

Is there a way to communicate between two Arduinos?

While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control. This communication could be achieved using either wired or wireless process.

How is the nRF24L01 connected to the Arduino?

To make the connection easier to follow and implement, a pin map showing which pins of the Arduino to which the RF module is connected, is shown below. It’s important that the NRF24L01 module’s VCC pin is not connected to the Arduino 5v pin as this will damage the NRF24L01 module. It is a 3.3V device.

How is amplitude shift keying used in Arduino?

This technique is called Amplitude Shift Keying (ASK). This is the RF receiver module. Even though it looks complex, it is as simple as the transmitter module. It consists of an RF tuner circuit, OP Amps, and a PLL. A couple of OP-Amps are used to amplify the carrier wave received from the transmitter.

How are communication protocols used in the Arduino?

Communication is an important process for transmitting and receiving data from and to the Arduino while doing projects. Moreover, there are hundreds of protocols available for performing this data exchange between an Arduino and other devices by using both wired and wireless pathways. We can classify all these protocols into two broad categories:

How much power does the Arduino nRF24L01 + use?

Since the NRF24L01+ uses power in the 15 mA range and the Uno listed a 3.3 V supply capability of 50 mA, a separate supply seems unnecessary. However, a capacitor can help even out power spikes or deficits from the Arduino.

What are the advantages of using Arduino board?
