Simple and Cheap Radio Control Making for RC Models. DIY RC
How to make a low cost 4 channel remote control for RC model aircraft, drones, cars and boats.
Construction of remote controls with proportional controls, which cost about 13-14 USD. It can be used for all kinds of model vehicle control such as model aircraft, drone, car, boat, tank.
Necessary materials:
2 x Arduino Nano
1 x NRF24L01 + PA Wireless Module
1 x NRF24L01 Wireless Module
2 x Arduino joystick
2 x 100uF Capacitor (16V or above)
1 x 13 * 6 cm PCB Board
1 x 5 * 3.5cm PCB Board
In tutorial we will learn how to build a DIY Arduino RC transmitter. Very often I need wireless control for the projects that I make, so therefore I built this multifunctional radio controller which can be used for pretty much everything.
You can watch the following video or read the written tutorial below.
Overview
Now I can wirelessly control any Arduino project with just some small adjustments at the receiver side. This transmitter can also be used as any commercial RC transmitter for controlling RC toys, cars, drones and so on. For that purpose it just needs a simple Arduino receiver which then generates the appropriate signals for controlling those commercial RC devices.
The radio communication of this controller is based on the NRF24L01 transceiver module which if used with an amplified antenna it can have a stable range of up to 700 meters in open space. It features 14 channels, 6 of which are analog inputs, and 8 digital inputs.
It has two joysticks, two potentiometers, two toggle switches, six buttons and additionally an internal measuring unit consisting of an accelerometer and a gyroscope which can also be used for controlling things with just moving around or tilting the controller.
Arduino RC Transmitter Circuit Diagram
To begin with, let's take a look at the circuit diagram. The brain of this RC controller is an Arduino Pro Mini which is powered using 2 LiPo batteries producing around 7.4 volts. We can connect them directly to the RAW pin of the Pro Mini which has a voltage regulator that reduced the voltage to 5V. Note that there are two versions of the Arduino Pro Mini, like the one I have that operates at 5V and the other operates at 3.3V.
On the other hand, the NRF24L01 module strictly needs 3.3V and it's recommended to come from a dedicated source. Therefore we need to use a 3.3V voltage regulator which is connected to the batteries and convert the 7.4V to 3.3V. Also we need to use a decoupling capacitor right next to the module in order to keep the voltage more stable, thus the radio communication will be more stable as well. The NRF24L01 module communicates with the Arduino using the SPI protocol, while the MPU6050 accelerometer and gyro module uses the I2C protocol.
