Note that if using a higher level it is recommended to use a bypass capacitors across GND and 3.3V of the modules so that they have more stable voltage while operating.

tPALevel(RF24_PA_MIN) Code language: Arduino ( arduino ) Then using the tPALevel() function we set the Power Amplifier level, in our case I will set it to minimum as my modules are very close to each other. radio.openReadingPipe( 0, address) Code language: Arduino ( arduino ) On the other side, at the receiver, using the tReadingPipe() function we set the same address and in that way we enable the communication between the two modules. radio.openWritingPipe(address) Code language: Arduino ( arduino ) In the setup section we need to initialize the radio object and using the radio.openWritingPipe() function we set the address of the receiver to which we will send data, the 5 letter string we previously set. We can change the value of this address to any 5 letter string and this enables to choose to which receiver we will talk, so in our case we will have the same address at both the receiver and the transmitter. const byte address = '00001' Code language: Arduino ( arduino ) Next we need to create a byte array which will represent the address, or the so called pipe through which the two modules will communicate.

RF24 radio ( 7, 8) // CE, CSN Code language: Arduino ( arduino ) The two arguments here are the CSN and CE pins. So we need to include the basic SPI and the newly installed RF24 libraries and create an RF24 object. } Code language: Arduino ( arduino ) Code Description

Just search for “rf24” and find and install the one by “TMRh20, Avamander”. We can also install this library directly from the Arduino IDE Library Manager.

Once we connect the NRF24L01 modules to the Arduino boards we are ready to make the codes for both the transmitter and the receiver.įirst we need to download and install the RF24 library which makes the programming less difficult. As an Amazon Associate I earn from qualifying purchases.
