Step 4: Arduino Transmitter & Reciver

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.


Overview

Now I can wirelessly control any Arduino project with just some small adjustments at the receiver side. This transmitter can be also 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.



I will explain how everything works in this video through few examples of controlling an Arduino robot car, controlling the Arduino Ant Robot from my previous video and controlling a brushless DC motor using an ESC and some servo motors.

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 be also 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 SPI protocol, while the MPU6050 accelerometer and gyro module uses the I2C protocol.

DIY Arduino based RC Transmitter Code

Let’s explain how the transmitter code works. So first we need to include the SPI and RF24 library for the wireless communication, and the I2C library for the accelerometer module. Then we need to define the digital inputs, some variables needed for the program below, define the radio object and the communication address.

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#include <Wire.h>


// Define the digital inputs
#define jB1 1  // Joystick button 1
#define jB2 0  // Joystick button 2
#define t1 7   // Toggle switch 1
#define t2 4   // Toggle switch 1
#define b1 8   // Button 1
#define b2 9   // Button 2
#define b3 2   // Button 3
#define b4 3   // Button 4

const int MPU = 0x68; // MPU6050 I2C address
float AccX, AccY, AccZ;
float GyroX, GyroY, GyroZ;
float accAngleX, accAngleY, gyroAngleX, gyroAngleY;
float angleX, angleY;
float AccErrorX, AccErrorY, GyroErrorX, GyroErrorY;
float elapsedTime, currentTime, previousTime;
int c = 0;


RF24 radio(5, 6);   // nRF24L01 (CE, CSN)
const byte address[6] = "00001"; // Address
Code language: Arduino (arduino)

Then we need to define a structure where we will store the 14 input values of the controller. The maximum size of this structure can be 32 bytes because that’s the NRF24L01 buffer limit or the amount of data the module can send at once.


/ Max size of this struct is 32 bytes - NRF24L01 buffer limit
struct Data_Package {
  byte j1PotX;
  byte j1PotY;
  byte j1Button;
  byte j2PotX;
  byte j2PotY;
  byte j2Button;
  byte pot1;
  byte pot2;
  byte tSwitch1;
  byte tSwitch2;
  byte button1;
  byte button2;
  byte button3;
  byte button4;
};

Data_Package data; //Create a variable with the above structure
Code language: Arduino (arduino)

In the setup section we need to initialize the MPU6050 module and we can also calculate the IMU error which is a values that is later used when calculating the correct angles of the module.


void initialize_MPU6050() {
  Wire.begin();                      // Initialize comunication
  Wire.beginTransmission(MPU);       // Start communication with MPU6050 // MPU=0x68
  Wire.write(0x6B);                  // Talk to the register 6B
  Wire.write(0x00);                  // Make reset - place a 0 into the 6B register
  Wire.endTransmission(true);        //end the transmission
  // Configure Accelerometer
  Wire.beginTransmission(MPU);
  Wire.write(0x1C);                  //Talk to the ACCEL_CONFIG register
  Wire.write(0x10);                  //Set the register bits as 00010000 (+/- 8g full scale range)
  Wire.endTransmission(true);
  // Configure Gyro
  Wire.beginTransmission(MPU);
  Wire.write(0x1B);                   // Talk to the GYRO_CONFIG register (1B hex)
  Wire.write(0x10);                   // Set the register bits as 00010000 (1000dps full scale)
  Wire.endTransmission(true);
}
Code language: Arduino (arduino)

You can find more details how MEMS accelerometer and gyro work here. A dedicated tutorial for the MPU6050 is coming soon.

Then we need to initialize the radio communication, activate the Arduino internal pull-up resistors for all digital inputs and set the initial default values for all variables.


// Define the radio communication
  radio.begin();
  radio.openWritingPipe(address);
  radio.setAutoAck(false);
  radio.setDataRate(RF24_250KBPS);
  radio.setPALevel(RF24_PA_LOW);

  // Activate the Arduino internal pull-up resistors
  pinMode(jB1, INPUT_PULLUP);
  pinMode(jB2, INPUT_PULLUP);
  pinMode(t1, INPUT_PULLUP);
  pinMode(t2, INPUT_PULLUP);
  pinMode(b1, INPUT_PULLUP);
  pinMode(b2, INPUT_PULLUP);
  pinMode(b3, INPUT_PULLUP);
  pinMode(b4, INPUT_PULLUP);
Code language: Arduino (arduino)

In the loop section start by reading the all analog inputs, map their values from 0 to 1023 into byte values from 0 to 255 because we already defined the variables in our structure as bytes. Each input is stored in the particular data variable from the structure.


// Read all analog inputs and map them to one Byte value
  data.j1PotX = map(analogRead(A1), 0, 1023, 0, 255); // Convert the analog read value from 0 to 1023 into a BYTE value from 0 to 255
  data.j1PotY = map(analogRead(A0), 0, 1023, 0, 255);
  data.j2PotX = map(analogRead(A2), 0, 1023, 0, 255);
  data.j2PotY = map(analogRead(A3), 0, 1023, 0, 255);
  data.pot1 = map(analogRead(A7), 0, 1023, 0, 255);
  data.pot2 = map(analogRead(A6), 0, 1023, 0, 255);
Code language: Arduino (arduino)

We should just note that because we use the pull-up resistors the digital pins readings are 0 when the buttons are pressed.

// Read all digital inputs
  data.j1Button = digitalRead(jB1);
  data.j2Button = digitalRead(jB2);
  data.tSwitch2 = digitalRead(t2);
  data.button1 = digitalRead(b1);
  data.button2 = digitalRead(b2);
  data.button3 = digitalRead(b3);
  data.button4 = digitalRead(b4);
Code language: Arduino (arduino)

So using the radio.write() function we simple send the values from all 14 channels to the receiver.


// Send the whole data from the structure to the receiver
  radio.write(&data, sizeof(Data_Package));
Code language: Arduino (arduino)

In case the toggle switch 1 is switched on, then we use the accelerometer and gyro data instead for the control.

if (digitalRead(t1) == 0) {
    read_IMU();    // Use MPU6050 instead of Joystick 1 for controling left, right, forward and backward movements
  }
Code language: Arduino (arduino)

So instead of the joystick 1 X and Y values we are using the angle values we are getting from the IMU, which we previously convert them from values from -90 to +90 degrees into byte values from 0 to 255 appropriately.

// Map the angle values from -90deg to +90 deg into values from 0 to 255, like the values we are getting from the Joystick
  data.j1PotX = map(angleX, -90, +90, 255, 0);
  data.j1PotY = map(angleY, -90, +90, 0, 255);
Code language: Arduino (arduino)

So that’s how the transmitter code, the most important things were defining the radio communication and sending the data to the receiver.

  data.j1PotY = map(angleY, -90, +90, 0, 255);
}



Receiver Code

Now let’s take a look at how we can receive this data. Here’s a simple Arduino and NRF24L01 receiver schematic. Of course you can use any other Arduino board.


And here’s a simple receiver code where we will receive the data and simply print it on the serial monitor so that we know that the communication works properly. Again we need to include the RF24 library and define the objects and the structure the same way as in the transmitter code. In the setup section when defining the radio communication we need to use the same settings as the transmitter and set the module as receiver using the radio.startListening() function.

  Serial.print(data.button1);
  Serial.print("; j2PotX: ");
  Serial.println(data.j2PotX); 
}

void resetData() {
  // Reset the values when there is no radio connection - Set initial default values
  data.j1PotX = 127;
  data.j1PotY = 127;
  data.j2PotX = 127;
  data.j2PotY = 127;
  data.j1Button = 1;
  data.j2Button = 1;
  data.pot1 = 1;
  data.pot2 = 1;
  data.tSwitch1 = 1;
  data.tSwitch2 = 1;
  data.button1 = 1;
  data.button2 = 1;
  data.button3 = 1;
  data.button4 = 1;
}
Code language: Arduino (arduino)

In the main loop using the available() function we check whether there is an incoming data. If true we simply read the data and store it into the variables of the structure. Now we can print the data on the serial monitor to check whether the transmission work properly. Also using the millis() function and an if statement we check whether we keep receiving data, or if we don’t receive data for a period longer than 1 second, then we reset variables to their default values. We use this to prevent unwanted behavior, for example if a drone has a throttle up and we lose connection it can keep flying away unless we reset the values.



So that’s it. Now we can implement this method of receiving the data for any Arduino project. For example here the code for controlling the Arduino Agriculture robot from my idea...

As an update to this project, I made a dedicated Arduino based RC Receiver. Again, it’s based on the Arduino Pro mini board and it has several ready to use servos and ESCs connections, placed on a compact PCB.



Step 5: Thanking to Instructables

Agricultural robots are automated machines that can perform tasks on farms or in agricultural environments. They can be programmed to perform specific tasks or be designed to react to their environment. 

Agricultural robots can perform crop maintenance tasks such as: Harvesting, Applying pesticides, Weeding. 

They can also operate in greenhouses. 

Agricultural robots can benefit farmers by: 


  • Filling labor gaps
  • Reducing labor costs
  • Performing dull or repetitive tasks
  • Taking on dangerous tasks

The agriculture robot market was valued at USD 7.07 billion in 2022 and is predicted to reach USD 24 billion by 2030. 


Some examples of agricultural robots include: 


  • Autonomous Mobile Robots (AMRs): These robots can haul fruits, vegetables, and potted plants.
  • EcoRobotix: This Swiss startup developed an autonomous robot that uses scan-and-spray technology to spot weeds.

Other types of robots used in horticulture include: 


  • Demeter
  • Fruit picking robots
  • Drones
  • Forester robot
  • Robot suit
  • Vitirover solar robot
