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 */ # include # include # include RF24 radio ( 7, 8) // CE, CSN const byte address = "00001" } Code language: Arduino ( arduino ) Receiver Code /* */ # include # include # include RF24 radio ( 7, 8) // CE, CSN const byte address = "00001" * Arduino Wireless Communication Tutorial Here are the two codes for the wireless communication and below is the description of them. 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.

MOSI and MISO are present only on the connector pads. On the ICSP connector only 5V, GND and RST are wired to the respective pins on the header. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins. Three screw holes allow the shield to be attached to a surface or case. The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. The Proto Shield bring the power from the Arduino standard 5V and GND pins to the two power bus rows placed between the Through Hole package footprint, which can be used for powering the DIP sockets, or for power and ground rows. Proto aerea with multiple THT pads, 100 mils pitch.32 double row through Hole pads, standard Arduino breakout layout.The Arduino Mega Proto Shield is open-source hardware!
