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.

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

Connect the NRF24L01 Module

these connections are applied for both, The transmitter and the receiver

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+

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

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
