loop() function will take care of listening for the payload and handling it.

setup() function initiate the module as receiver with the provided configuration.

The connection will be considered as lost after INTERVAL_MS_SIGNAL_LOST milliseconds. We will be listening for the struct defined in the transmitter (called payload ). Greater level = more consumption = longer distance Append ACK packet from the receiving radio back to the transmitting radio NRF24L01 buffer limit is 32 bytes (max struct size)

loop() function will take care of updating the payload values and sending them.

setup() function initiate the module as transmitter with the provided configuration.We've defined a struct (called payload ) which will be sent every INTERVAL_MS_TRANSMISSION milliseconds. It will include the library with predefined functions to interact with module. Then you can simply use include statement: #include 'RF24.h' In case you are using different Arduino board, it is advisable to check the Arduino official documentation before proceeding. However, pin D10 is a special pin, it must be set as OUTPUT for the Arduino Nano to operate as an SPI master. The CE and the CSN pins can be connected to Arduino Nano D9 and D10 respectively (you can use any pins). We've used Arduino Nano and these pins are as follows: This means that the MOSI, MISO, and SCK pins must be connected to their corresponding pins on the microcontroller. The module acts as an SPI slave, which means that it can only be used with devices that have dedicated SPI communication lines. The NRF24L01 module communicates with the Arduino using SPI protocol. The adapter works identically for both versions and has the same pinout as original boards. This range extender chip along with external antenna helps the module achieve about 1000m. The second version (on the right) integrates the PA, LNA, and transmit-receive switching circuitry. With this version, you’ll be able to communicate over a distance of 100 meters (range indoors, especially through walls, will be slightly weakened). In general, this means that the UNO put several functions on one pin and these have moved to separate pins on the Mega. Red are differences, where the functionality has moved on Mega2560 compared to UNO. Green have the same function and position as the Arduino UNO R3. This allows for a more compact version of the breakout. Inspired by Nick's UNO pinout I did a similar one for the Arduino Mega2560 R3. Provide 8-bit PWM output with the analogWrite() function.The first version (on the left) uses on-board antenna. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.

Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
