The aim of this project is to build a transmitter and a receiver by using a cheap and easy to use component such as Arduino UNO, Arduino Nano, and nRF24L01 transceiver. This project is a simple and easy to implement and can be a good start point for beginners.
Step 1: ?What you will need:
1x Arduino Uno 1x Arduino Nano (v3.0) 2x nRF24L01 Module 14x Male-To-Female jumper wire (different colors) 6x Male-To-Male jumper wire 1x Breadboard R/C car equipped with: 1x Servo motor 1x Electronic Speed Controller (ESC) I am using HSP, sp-03018 1x 7.2V 1800 mAh Ni-Mh battery 1x or 2x Joystick Module for Arduino 1x 2.2 K Resistor Led
Step 2: Connect the nRF24L01 module
these connections are applied for both, The transmitter and the receiver
Step 3: Connect the joystick and the LED to the transmitter
And connect the LED as following: LED+ --> Arduino Nano D2 pin LED- --> Arduino Nano GND 2k2 Resistor --> LED+
Step 4: Connect the ESC and The Servo to the Receiver board
IMORTANT NOTE: if you have a similar ESC Never connect the ESCís red wire to the Arduinoboard because it may damage it
Step 5: Power source
I've attached this header to the battery -as shown in picture- in order to deliver a power to the Arduino on the receiver side, or you can use a separated battery for the Arduino board.for the transmitter you can use any power source as you wish
Step 6: Programming the Arduinos
Download the RF24 Library from hereThe sketch is available at github and it is full commented, or you can download it from the attachments.
