RF Control System for R/C Vehicle Based on Arduino and NRF24L01

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 ESC’s 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
