In this tutorial we will learn how to interface the nrf24l01 with arduino by controlling the servo motor connected with one arduino by varying the potentiometer on the other arduino.

Walkie talkie using arduino and nrf24l01. For the sake of simplicity we have used one nrf24l01 module as transmitter and the other is receiver but each module can be. Irq to digital pin 2 i used the nrfl01 rf transceiver from nordic semiconductor for this project. The nrf24l01 module works with the arduino through the spi communication. That s how i found the excellent rf24audio library.

Miso to digital pin 12 8. Csn to digital pin 8 5. We have already learned how to interface nrf24l01 with arduino by controlling a servo motor remotely. The main component of this project is the nrf24l01 rf module and arduino uno which is the brain or processor.

Ground to ground 2. The pinout of the module is as follows. To interface the arduino with the module we ll be using tmrh20 s rf24 library which conveniently packages the low level communications between the rf module and the mcu into an easy to use c class. Arduino walkie talkie with nrf24l01 one of the more popular projects i build with kids is my arduino morse radio so i started to wonder whether the nrf24l01 can also transmit sound.

Sck to digital pin 13 6. Walkie talkie using nrf24l01 rf module. For this project the nrf24l01 rf module is chosen because it has several advantages over a digital communication medium. Interfacing nrf24l01 with arduino.

Mosi to digital pin 11 7. Nrf24l01 2 4ghz transceiver module. The operating voltage of this module is from 1 9 to 3 6v but the other pins are 5v tolerant which means that the other pins can be directly connected to the arduino. Vcc to 3 3 v not 5 v 3.

Bi directional communication by both the buyer to make your project can use both the transmitter module.
