Step 2: NRF24L01

nRF24L01 2.4GHz Radio/Wireless Transceivers

There are many options how to connect your Arduino wireless. One of options available is nRF24L+

Step 3: Connections

The module communicates with the controller via SPI interface.

You must use this module with capacitor or power adapterfor correct 3.3V

Step 4: RF24 Library

You must download and install the RF24 library for using nRF24L+ module. You can download from GitHub

Step 5: Source Code

I created two code, one of for the transmitter and other one for the receiver. You can only copy and paste the code into empty page of the Arduino IDE.

hello sir how can i control a dc motor instead of a servo.thank you

Hi,

I'm sorry you do not really speak English! I copy the receiver code to Arduino IDE 1.0.6 and 1.8.3.

I copied the RF24 master library to the right place.

I press the check button and the software writes the error messages on the screen.

There is a problem with this line item:

done = radio.read(msg, 1);

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Arduino: 1.0.6 (Windows NT (unknown)), Board: "Arduino Uno"
Receiver.ino: In function 'void loop()':
Receiver:32: error: void value not ignored as it ought to be

Sincerely

Zoltan Nagy

What is the meaning of the picture with an exclamation mark? Is that mean that we have to do or we dont do that?
