![]() Next, create a byte array representing the address, and create two pipes or addresses for the bi-directional communication. You read the output from terminal 2 of the potentiometer.Īrduino Code for nRF24L01 (Transmitter with Potentiometer) #includeĬonst byte addresses = Step 3: Connect the 1st terminal of POT to the GND and the 3rd terminal of POT to +5V VCC on the Arduino Uno Board.Ĭonnect the 2nd terminal of POT to the A0 pin of the Arduino Uno board. Connect one side to the ground and the other side to digital pin 2 of Arduino Uno. Step 2: Plug the push button in the middle of the breadboard. Step 1: Connect Arduino Uno to nRF24L01 as mentioned in the table. Wiring diagram of nRF24L01 module with Arduino Uno as Transmitter Now, follow the below-mentioned steps to connect the nRF24L01 Transceiver module and other components with the Arduino Board. Here, I’m using an Arduino Uno Board used as a Transmitter and Arduino Mega Board used as a Receiver. Remote sensors for temperature, pressure, alarms, etc.Applications of the NRF24L01 Wireless Transceiver Module: ![]() > Read our guide about What You Can Build with Adruino. These SPI pins depend on microcontrollers. The nRF24L01 module uses the SPI ( Serial Peripheral Interface) slave communication protocol with a maximum data rate of 10Mbps. The nRF24L01 Transceiver RF module has an address range of 125 to communicate with the other 6 modules and allows several wireless units to communicate simultaneously in a specified location.Įach channel occupies a bandwidth of less than 1MHz. This pin is an interrupt pin that can alert the master when new data is available to process. This pin is SPI output from the nRF24L01 module. The only SPI bus Master that provides clock pulses. When this pin goes low, the nRF24L01 begins listening on its SPI port for data and processes it accordingly. This pin is an active-LOW pin and is usually kept HIGH. When selected, the nRF24L01 will either transmit or receive, depending on its current mode. It can be anywhere from 1.9 to 3.9 volts. NRF24L01 Transceiver Module has 8 pins available, which are used for data sent or received. It gives a short switching time, enabling frequency hopping.It provides auto ACK, retransmits, address, and CRC computation.The module consists of a single chip GFSK transceiver with OSI link layer hardware.It can operate with baud rates from 250Kbps up to 2 Mbps.250mA is the maximum operating current.The NRF24L01 specifications and features are given below. nRF24L01 transceiver module specifications and features: If you want more technical details, check the: nRF24L01 datasheet. This module can cover 100 meters (200 feet) whenever it operates efficiently.Īlthough the module’s operating voltage ranges from 1.9V to 3.6V, it has 5V tolerant pins so that you can connect them directly to the Arduino. ![]() The NRF24L01 wireless Transceiver RF module is cheap, and it is a Half-Duplex type module, which means it can either send or receive data at a time. NRF24L01 operates at the 2.4GHz ISM band and is used for wireless communication. Using the nRF24L01 transceiver module, two or more microcontroller boards that have no wireless facilities can communicate with each other wirelessly over a distance. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to products on. ![]()
